ICL5102

The Infineon ICL5102 is a 2nd generation, highly integrated controller combining PFC (Critical Conduction Mode/Discontinuous Conduction Mode) and Resonant Half-Bridge (HB) functionalities. This integration reduces external component count, optimizes the Bill of Materials (BOM), and improves form factor. It supports a universal AC input voltage range of 90 to 305 Vrms, achieving excellent system efficiency up to 94% and low Total Harmonic Distortion (THD) below 5% down to 30% nominal load.

The Resonant HB controller supports fixed or variable switching frequency control, with a maximum HB switching frequency of 500 KHz and soft-start up to 1.3 MHz. Burst Mode ensures power limitation and low standby power consumption below 300mW. The device includes an integrated High Side MOSFET driver and a comprehensive set of protection features with auto-restart, including input brown-out, PFC bus over-voltage, PFC over-current, output over-voltage (OVP), output over-current/short circuit (OCP), output over-power/over-load (OPP), capacitive mode protection, and external over-temperature protection (OTP).

Packaged in a small DSO-16 package, the ICL5102 is suitable for offline LED drivers for commercial and industrial lighting up to 350 W, as well as high-density AC/DC power supplies. It is qualified for industrial applications according to JEDEC standards.
