CL88020数据手册集成电路（IC）的LED驱动器规格书PDF

描述 Description

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.

简介

CL88020属于集成电路（IC）的LED驱动器。由制造生产的CL88020LED 驱动器器件属于 LED 驱动器电源管理集成电路 (PMIC) 系列，可通过标称固定电压的电源为负载（通常为发光二极管）提供电流，并且电流可控。它与用于电压调节的类似产品的主要区别在于，这类器件提供较低的反馈电压（以提高系统能效），而且通常可对器件工作点进行外部控制，可在照明应用中用于实现调光功能。
