1.2 CL88030 OVERVIEW

The CL88030 driver Integrated Circuit (IC) is a sequential linear LED driver, 4-tap
version, targeted to provide a flexible solution to drive LEDs from AC line voltages up
to 277 V

A sequential linear LED driver is an LED driver, operating from an AC voltage source
and comprised of multiple linear current regulators driving various tap points along a
long string of LEDs connected to the rectified AC. High efficiency is achieved by
shutting off upstream regulators when downstream regulators achieve regulation.

The CL88030 is in a DFN-10 package. The power dissipation for this device is much
lower than the CL8800 or CL88020 one, due to the external FETs. The bottom tab is
not necessary for thermal reasons, but it is necessary to provide 11 electrical
connections for the CL88030.

BOARD (ADM00860)?

The CL88030 230 V
designated LED Load Board (ADM00861) represent a complete solution for a LED
lighting application, powered directly from the 230 V
Technology's CL88030 sequential linear LED driver. The application achieves efficient
operation without 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 the need of 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
CL88030 is compatible with both leading-edge and trailing-edge dimmers.

Note: The LED Load (ADM00861) 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 a double-sided adhesive
thermal tape necessary to mount the LED Load on it. The LED Load is also
developed to be used with another LED Driver board from the CL88 series
(ADM00866, CL8800 LED Driver Board), 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 NTC thermistor by mounting the jumper between positions 2 and
3 of the J4 header.

2.1 INTRODUCTION

CL88030

230 VAC OFFLINE LED DRIVER

EVALUATION BOARD USER’S GUIDE

The CL88030 230 V
string of inexpensive, low-current LEDs directly from the AC mains. A basic driver cir­cuit consists of the CL88030, six resistors, four FETs and a bridge rectifier. Two to four
additional components are optional for various levels of transient protection, also with
a low-price NTC to assure remote OTP. No capacitors, EMI filters or power factor
correction circuits are needed.

The operation principle is identical to the CL88020 one, the difference being the output
FETs that are outside the IC and so, the power capability of the application is higher
and the input/output capability is also higher. A string of series/parallel LEDs is tapped
at four locations. Four linear current regulators sink current at each tap through a single
control point and are sequentially turned on and off. High efficiency is achieved by shut­ting off upstream regulators when downstream regulators achieve regulation. This
makes controlling overall input current easier than trying to control multiple current
paths, thereby tracking the input sine wave voltage. Voltage across each regulator is
minimized when conducting, providing high efficiency. It implements a self-commuta­tion technique using only the tap currents. This technique inherently provides smooth
transitions from one regulator to the next, without relying on tap voltages or the rectified
AC to coordinate the transitions. The current waveform can be tailored to optimize for
input voltage range, active line/load regulation, output power/current, efficiency, power
factor, THD, dimmer compatibility and LED utilization. With the addition of a Resis­tor-Capacitor (RC) network, the driver is compatible with a wider range of phase-cut
dimmers. The data sheet includes a description of the driver’s operation mode, with
design guidelines and examples. Additional topics include optimization/tradeoffs in per­formance (output power, efficiency, LED utilization, driver dissipation, output ripple,
component selection, input current THD, PF and line regulation). Transient protection,
OTP and ripple reduction circuit are also covered. Explanations are provided for tap
sequencing, active line regulation and OTP.

and demonstrate the CL88030 LED Driver.

Offline LED Driver evaluation board is fully tested to evaluate

AC

WARNING

The ADM00860 source board and ADM00861 LED Load board 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!

Consider the following recommendations before starting the setup process:

• Place the CL88030 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 in danger the person conducting the tests.

2.2.1 Prerequisites

Since the power of the application is about 15 watts, for a continuous 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, make 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 (ADM00861) to the heat sink.

6. Slowly press the top of the PCB to be sure that the thermal contact will be made

all over the board.

5. Use a colored plexiglass above the LED Load board for eyes protection against
extreme light.

6. Plug the power cord into a 230 V

outlet and apply 230 VAC±15%, 50 Hz. While

AC

it is possible for the values to be below this range, it is recommended not to
exceed 277 V

. In this case, the transient protection feature is automatically

AC

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
0V

to 300 VAC. This can also be obtained from an auto-transformer supplied from

AC

the mains or an electronic AC/AC power supply (for example, the Chroma ATE Inc.
61500 series).

Note: Auto-transformers do not provide isolation from the utility mains.

Figure 2-1 illustrates the connection between ADM00860 and ADM00861.

2.4 HOW DOES THE CL88030 230 V
BOARD SET WORK?

The CL88030 230 V
the current through the four LED taps while maintaining a high-input power factor (PF)
and low THD. The ADM00860 includes a CL88030 IC, which is a sequential linear LED
driver controlling four taps. 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:

• The first is a single-point control. All tap currents pass through a single control
point. This makes controlling overall input current easier than trying to control mul­tiple current paths.

• The second concept is called self-commutation. Using only the tap currents
themselves, this technique inherently provides smooth transitions from one regu­lator 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 CL88030 230 V
necessary to perform, as well as OTP, Active Line Regulation (ALR) and Ripple
Reduction Circuit (RRC).

The OTP operates linearly, gradually reducing the output power as temperature
increases. To accomplish this it uses an inexpensive, external NTC thermistor to
remotely sense LED temperature. The thermistor is located on the LED Load board, in
close proximity to the LEDs, providing near-direct LED temperature monitoring. The
OTP temperature is adjustable via selection of the NTC resistance.

The ALR circuit maintains fairly constant output power over variations in AC line
voltage. It is not a closed loop system that directly monitors and corrects output power.
Instead, it monitors the average voltage applied to the LED string and uses it to adjust
the reference voltage provided to the tap current regulators.

The RRC providing low output ripple is achieved using a capacitor and four diodes. The
capacitor may consist of one or more paralleled ceramic capacitors or electrolytic. The
CL88030 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 the idle. This
reduces overall ripple, which means about 0.15 flicker index.

For more information, see the CL88020 data sheet.

2.5 BOARD TESTING

To start testing the evaluation board, follow these steps:

1. Connect the input AC source and the output LED Load, as shown in Figure 2-1.

2. Use an eye protection filter to check that all the four taps light up on the LED Load
Board.

3. Power the board at 230 V

4. Verify each tap current through the LEDs. It should be within a range of 65 mA
and 134 mA. It can be measured by separating each wire from the
inter-connection 10-wire flat cable between the CL88030 LED Driver board and
the CL88030 LED Load board.

5. If a variable AC source is available, set the input voltage to any value between
180 V
