1.4 OVERVIEW OF THE CL8800 230 VAC OFFLINE LED DRIVER EVALUATION
BOARD
The CL8800 230 VAC Offline LED Driver Evaluation Board (ADM00866) and a
designated LED Load Board (ADM00861) represent a complete lighting solution,
powered directly from the 230 VAC line and based on Microchip Technology's CL8800
sequential linear LED driver. The application achieves efficient operation without using
any magnetics or conventional switching techniques and is a flexible solution that
allows users to design and test their own LED Load. The available LED Load is made
with 12 LEDs. Since no high frequencies are present, it exhibits inherently low
conducted and radiated EMI without needing input filters or shielding. Because the
current through the LEDs follows the AC input voltage, Power Factor Correction (PFC)
circuitry is not needed. With the addition of an RC network, the CL8800 is compatible
with both leading-edge and trailing-edge dimmers.
The LED Load is provided on a double-layer 60 mm diameter FR4 (0.6 mm thick) PCB,
ready to be mounted on a pin-fin heat sink. The kit includes a black anodized pin-fin
heat sink and double-sided adhesive thermal tape to mount the LED Load on it. The
LED Load is also developed to be used with other LED Driver boards from the
CL88XXX series, so it is equipped with a selectable (by means of a jumper) NTC or
PTC thermistor, making overtemperature protection (OTP) possible. For the current
application, the selection activates the PTC by mounting the jumper between positions
1 and 2 of the J4 header.
The LED Driver PCB (ADM00866) is made on a 1.6 mm standard double-layer FR4.
The kit includes a 10-wire flat cable to connect the LED Driver Board to the LED Load.
All circuitry and hardware is provided, along with transient protection and
overtemperature protection. Plug into a 230 VAC outlet (50 Hz or 60 Hz) to get started.

Chapter 2. Installation and Operation
2.1 INTRODUCTION
The CL8800 230 VAC Offline LED Driver Evaluation Board is intended to drive a long
string of low current LEDs directly from the 230V AC mains. A basic driver circuit con-
sists of CL8800, six resistors and a bridge rectifier. Two to four additional components
are optional for various levels of transient protection, also with a low-price PTC to
assure remote OTP. No capacitors, EMI filters or power factor correction circuits are
needed.
A string of series LEDs is tapped at four locations, the next two outputs being populated
with Zener diodes from economic considerations (fewer taps reduce costs). It is
economically inefficient to populate the last two taps with LEDs since they are lit for a
very short time when the voltage is near the peak of the input voltage sinus wave.
Regarding the application requirements, the user can have six taps populated with
LEDs because higher taps increase the efficiency and lower the THD. Six linear current
regulators sink current at each tap and are sequentially turned on and off, tracking the
input sine wave voltage. Voltage across each regulator is minimized when conducting,
providing high efficiency. Output current at each tap is individually resistor-adjustable.
Cross-regulation, as the CL8800 switches from one regulator to another, provides
smooth transitions. The current waveform can be tailored to optimize for input voltage
range, line/load regulation, output power/current, efficiency, power factor, THD, dimmer
compatibility and LED utilization. With the addition of a Resistor-Capacitor (RC) net-
work, the driver is compatible with a wider range of phase-cut dimmers. The data sheet
includes a description of how the driver operates, with design guidelines and examples.

DS50002764A-page 14 2018 Microchip Technology Inc.
• Two 0 Resistors (R2 and R3) to Select the First Tap Series LED Count. R2 is
Present by Default.
2.2 GETTING STARTED
The CL8800 230 VAC Offline LED Driver Evaluation Board is fully tested to evaluate and
demonstrate the CL8800 LED Driver.
Take into account the following recommendations before starting the setup process:
• Place the CL8800 LED Driver Evaluation Board and the LED Load assembly on a
non-conductive surface when connected to the AC line.
• Do not come into contact with any of the two demonstration unit boards while they
are connected to the AC line.
• Disconnect the demonstration units from the AC line before performing any work
on any of them.
• Do not connect instruments having earth-referenced inputs, such as most
oscilloscopes (use isolation transformers).
• It is suggested that utility power for testing is provided from an AC source with a
floating output, and that differential voltage probes are used.
Failure to adhere to these guidelines may result in damage to the demo unit, the test
instruments, and/or can put the person conducting the tests in danger.
2.2.1 Prerequisites
Since the power of the application is about 10W, for a longer operation of the LED Load
(more than 30s), attach the provided heat sink using the double-sided adhesive thermal
tape by following these steps:
1. Before you start, be sure that the surface of the heat sink and of the PCB are dry
and clean (use cotton-made smooth material to clean if needed).
2. Detach the protection foil on the thermal tape from one side.
3. Attach the open portion of the thermal tape to the base of the heat sink.
4. Detach the second protection foil from the thermal tape.
5. Attach the PCB to the heat sink.
Slowly press on the top of the PCB to be sure that the thermal contact will be made all
over the board.
WARNING
The CL8800 LED Driver Evaluation Board (ADM00866) and CL8800 LED Load Board
(ADM00861) do NOT provide electrical isolation between the AC line and the lamp
circuitry. Dangerous voltages are present when connected to the AC line. Exercise
caution!

2.3 SETUP PROCEDURE
Powering the CL8800 230 VAC Offline LED Driver Evaluation Board is easy. The only
connections to be made are from the LED Driver Board to the LED Load assembled on
a pin-fin heat sink, using the provided 10-wire flat cable, and from the LED Driver Board
to the AC line via the power cord.
Follow these steps:
1. Read the above recommendations and precautions.
2. Set the jumper J4 on the LED Load Board between positions 1 and 2 to activate
the PTC for the OTP (this is specific when using the LED Load with ADM00866).
3. Connect the CL8800 LED Driver Evaluation Board and the CL8800 LED Load
Board by means of the provided 10-wire flat cable, between J2 and J3 connec-
tors. It is recommended to exercise caution, as the connectors on the flat cable
are protected from being connected incorrectly.
4. Connect the power cord on J1 on the LED Driver Board. The input connector J1
is placed on the left side of the LED Driver board, which is marked with the
inscription: AC.
5. Use a colored plexiglass above the LED Load Board for eye protection against
extreme light.
6. Plug the power cord into a 230 VAC outlet and apply 230 VAC ±15%, 50 Hz. While
it is possible for the values to be below this range, it is recommended not to
exceed 265 VAC. In this case, the Transient Protection feature is automatically
activated. Line frequency is not critical (50 Hz or 60 Hz).
A variable AC power supply is needed for testing and evaluation in the laboratory. The
power supply requires an output capability of at least 20W and a voltage range from
0 VAC to 270 VAC. This can also be obtained from an autotransformer supplied from the
mains or an electronic AC/AC power supply (for example, the Chroma ATE Inc. 61500
series).
Figure 2-1 illustrates the connection between ADM00866 and ADM00861.

2.4 HOW THE CL8800 230 VAC OFFLINE LED DRIVER EVALUATION BOARD
WORKS
The CL8800 230 VAC Offline LED Driver Evaluation Board is designed to control the
current through the six taps, four with LEDs and two populated with Zener diodes, while
maintaining high-input power factor (PF) and low THD.
Zener diodes may be substituted for LEDs for the upper taps of the string. The last one
or two taps of the LED string contribute little to the light output – they are mainly present
to offload the adjacent upstream regulator at high-line voltages to minimize losses. The
advantages of Zener substitution include minimizing unlit LEDs at low line for better
light uniformity, better line regulation at high line, fewer LEDs for lower cost and less
PCB area, and fewer board-to-board connections. Disadvantages include slightly
reduced efficiency at high line and additional heat load on the driver board.
The CL8800 230 VAC Offline LED Driver Evaluation Board includes a CL8800 IC, which
is a sequential linear LED driver controlling six taps of an LED string. Tap sequencing
assures the regulators are turned on and off at the proper times. Tap sequencing also
controls the smooth transition from one regulator to the next, without generating
EMI-causing glitches in input current. Two concepts are involved:
• Output current at each tap is individually resistor-adjustable.
• The second concept is called self-commutation. Using only the tap currents
themselves, this technique inherently provides smooth transitions from one regu-
lator to the next without relying on tap voltages or the rectified AC to coordinate
the transitions. This avoids having to monitor high voltages and is more precise.
These two concepts work together to properly sequence the current regulators and to
provide glitch-free operation and thus avoiding conducted EMI.
The CL8800 230 VAC Offline LED Driver Evaluation Board contains all the circuitry
necessary to perform, as well as OTP, and output light ripple reduction circuit.
The OTP is implemented using a single non-linear positive temperature coefficient
resistor (PTC) in series with the current-setting resistors. This uses an inexpensive,
external 2.2 to 3.3 standard PTC thermistor to remotely sense LED temperature.
The thermistor is located on the LED Load Board, in close proximity to the LEDs, pro-
viding near-direct LED temperature monitoring. At a critical temperature (around 85°C),
the resistance of the PTC rapidly increases manifold. At this point, the PTC resistance
becomes significant compared to the current-setting resistor and begins reducing LED
drive current. If a different critical temperature value is desired, simply replace the sup-
plied PTC (R4 on the LED Load) with another low-resistance PTC with the desired
thermal response. Paralleling the PTC with an ordinary resistor is another way to
control thermal response.
The Ripple Reduction Circuit (RRC) providing low output ripple is achieved using a
capacitor (C2, C3) and four diodes (D2, D3). The capacitor may consist of one or more
paralleled ceramic/electrolytic capacitors. The CL8800 with RRC operates in four
phases: recharge, hold-up, direct, and under certain conditions, idle. All active current
paths include Segment 1 (TAP1), assuring uninterrupted light output on it during all
phases of operation, excluding idle. That is why it is important to have a much greater
number of LEDs on TAP1 (6 LEDs in this case) compared to the rest. This reduces
overall ripple.
For more information, see the CL88020 data sheet.
The Mindi™ analog simulator of the CL8800 can be used to adjust tap resistors. To run
