Infineon Technologies AG AC-DC PWM-PFC Controller, Half-bridge and LLC controller ICE2HS01G

Infineon ICE2HS01G is a high performance resonant mode controller designed especially for high efficiency half-bridge or full-bridge LLC resonant converter with synchronous rectification at the secondary side. With its new driving techniques, the synchronous rectification can be realized for LLC converter operated with secondary switching current in both CCM and DCM conditions. No special synchronous rectification controller IC is needed at the secondary side. The maximum switching frequency is supported up to 1MHz. Except the patented SR driving techniques, this IC provides very flexible design and integrates full protection functions as well. It's adjustable for maximum/minimum switching frequency, soft-start time and frequency, dead time between primary switches, turn-on and turn-off delay for secondary SR MOSFETs. The integrated protections include input voltage brownout, primary three-levels over current, secondary over load protection and no-load regulation.
