SIC9762B

Features
·Active PFC for High power factor and low THD
·Built-in HV start-up and IC power supply circuit,
The VDD power supply resistors and power
feedback circuits from LED chips are not needed

General Description
The SIC9762B/9763B/9764B/9767B are built-in HV start-up and IC power supply circuit, main
line power up constant current LED regulators with high current accuracy which applies to single
stage step-down power factor corrected LED drivers. 600V power MOSFET is integrated, which
can significantly simplify the design of LED lighting system.

High accuracy of output current is achieved by sampling the output current directly. Quasi
Resonant (QR) Buck topology reduces the switching losses and largely increases the efficiency.

The SIC9762B/9763B/9764B/9767B are supplied from the main line, the VDD power supply
resistors and power feedback circuits from LED chips are not needed, save cost and help for
assemble efficiency.

The SIC9762B/9763B/9764B/9767B have multi-protection functions which largely enhance the
safety and reliability of the system, including VDD over-voltage protection, VDD UVLO,
short-circuit protection, LED open protection, cycle-by-cycle current limit and over-temperature
protection.

The SIC9762B available in SOP-7 package, SIC9763B available in SOP-7 & DIP-7package,SIC9764B available in DIP-7 package, SIC9767B available in SOP-7 package.
