General Description

The ICL3203 is a single stage step-down type constant current LED driver with power factor correction.

The ICL3203 is supplied from the line directly without auxiliary winding or external VDD capacitor, so the system BOM cost and size are minimized. It also provides precise output current control and digital compensation technology to ensure high output current accuracy and high power factor.  

The ICL3203 offers various protection functions to improve the system reliability, including LED open circuit protection, LED short circuit protection, and over-temperature protection.
