Device Overview

Summary

The CL88030 and CL88031 LED Driver Integrated Circuits (ICs) are intended offline sequential linear LED drivers designed to provide LED power from a utility voltage input.

The CL88030/31 devices are designed to drive a long string of inexpensive, low-current LEDs directly from the AC mains. A basic driver circuit consists of Microchip’s CL88030/31 LED driver IC, four power FETs (six if using the CL88031), four resistors, two capacitors, and a bridge rectifier. Additional components are optional for various levels of transient protection. Adding an inexpensive NTC-thermistor assures over temperature protection (OTP). No EMI filters or power factor correction circuits are needed (unless the optional flicker-reduction feature is desired).

A string of series/parallel LEDs is tapped at four (or six) locations, called “taps”. 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 by tracking the input sine wave voltage.

The CL88030/31 uses a self-commutation technique 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.

Additional Features
  • Suitable for 120VAC/230VAC/277VAC Nominal Input Voltage
    • - ± 15% input voltage tolerance recommended
  • Programmable Overtemperature Protection
    • Provides gradual reduction in light output with increasing temperature
  • Active Line Regulation
    • Provides fairly constant output power over variations in AC line voltage
    • Adjustable “knee” of regulation
  • 4 Taps (CL88030) or 6 Taps (CL88031) with Two Current Set Resistors
    • Allows optimization of THD
  • Optional Reduced Flicker Index
    • Provides near-continuous power to the LEDs
    • Reduces strobing
    • Uses an external capacitor
  • Compatible with Phase-cut Dimming, both Leading and Trailing Edge
