== ISO/TS 16949 ==
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in th intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not mean that we are guaranteeing the product as “unbreakable.”

EVALUATION BOARD USER’S GUIDE
This chapter provides an overview of the CL88030 230 V ation Board and covers the following topics:
• CL88030 Overview
• CL88030 Key Features
• What is the CL88030 230 V
• What the CL88030 230 V

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.

Offline LED Driver Evalu-
AC
Offline LED Driver Evaluation Board (ADM00860)?
AC
Offline LED Driver Evaluation Board Kit Contains
AC
• Scalable:
- AC line voltage limited only by external FETs
- Output power limited only by external FETs
• No Inductors:
- Reduces BOM cost and circuit complexity
• Efficient Operation:
- Typical electrical efficiencies of 80% to 90% across the AC input voltage
range
• No High Frequencies:
- Inherently low-conducted EMI, no need for input filters
• Inherently Dimmer Compatible:
- Works with most leading-edge and trailing-edge phase-cut dimmers
- Requires no special circuitry to detect and to handle dimmers
- May require an RC network across the AC line to provide adequate TRIAC
latching current
• Two Versions - 4-tap (CL88030) and 6-tap (CL88031):
- Higher taps increase efficiency and lower Total Harmonic Distortion (THD)
- Fewer taps reduce costs
2018 Microchip Technology Inc. DS50002772A-page 9
CL88030 230 VAC Offline LED Driver Evaluation Board User’s Guide
• Reduced Output Ripple (optional):
- An external capacitor with four diodes provides lower output ripple
- Strobing occurs at low line
- Provides continuous power to the driver
• Active Line Regulation:
- Active circuitry provides better regulated output power over variations in AC line voltage
- –12%/+0% line regulation typical
- Prevents driver from overheating at high AC line voltages
- Prevents excessive currents at low line
- Required for reasonable line regulation and efficient operation, given only four or six taps
- If unused, the ALR pin is left open in the application
• Overtemperature Protection (OTP), Optional:
- An inexpensive external NTC thermistor provides remote temperature sensing. The thermistor may be near the LEDs to provide nearly direct monitoring of LED temperature.
- OTP is linear (no on/off cycling)
- A widely available, 470 k NTC provides an 85°C maximum temperature
- Temperature adjustable via selection of NTC thermistor resistance
- If unused, the OTP pin is tied to BIAS
• Two Current-setting Resistors:
- Different hold-up and direct AC currents lower the THD and output ripple
- Tap current ratios internally set
- Reduces component count
- Fewer pins
- Simplifies application design
- Single-point current control for reduced EMI

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.
