Infineon - ICL5102 - High performance PFC + resonant controller for LCC and LLC

Infineon – ICL5102 – High performance PFC + resonant controller for LCC and LLC

The ICL5102 resonant controller IC is designed specifically for power supply and lighting drivers and has integrated PFC and HB controllers. It supports universal input voltages ranging from 70 VAC to 325 VAC, and has a comparable wide output range. A low number of external components are required to configure and support this controller IC. All parameters are set by resistors. The ICL5102 supports fast startup under 500 ms at less than 100 μA. The best-in-class power factor correction (PFC) is greater than 99 % and Total Harmonic Distortion (THD) is less than 3.5 %. The controller has up to 94% efficiency by resonant topology. The active burst mode for low standby under 300 mW with an enable/disable function supports dimming.

The PFC controller features adaptive soft-start, brownout detection, improved THD and adjustable PFC. The resonant HB controller has a fully integrated 650 V high-side driver with self-adaptive dead time ranging between 250 ns and 750 ns. It can detect overload, short circuit, over voltage, and over temperature.
