Device Overview

Summary

The CL88020 LED Driver Integrated Circuit (IC) is an off-line sequential linear LED driver designed to provide 8.5W of LED power from a 120 VAC nominal input voltage. CL88020 is designed to drive a long string of inexpensive, low-current LEDs directly from the AC mains. A basic driver circuit consists of Microchip Technology Inc.’s CL88020 LED driver IC, six resistors and a bridge rectifier. Two to four additional components are optional for various levels of transient protection, also with a low-cost NTC to assure remote over-temperature protection (OTP). No capacitors, EMI filters, or power factor correction circuits are needed unless the optional reduced light output ripple feature is desired.
