The ICE1HS01G-1 from Infineon Technologies is a Dual Output Half-Bridge Resonant AC-DC Converter that steps down an AC input voltage of 100 - 240 V to a DC output voltage of 1.5 - 9 V. It has a switching frequency of 47 - 53 kHz. This converter is specially designed to drive LLC resonant half-bridge converter designs and regulates the output voltage by changing the switching frequency. It integrates an oscillator to allow the designers to set a suitable operating frequency range with a resistor.

This RoHS-compliant AC-DC converter provides an adjustable hysteresis to the mains input for under-voltage protection (UVP), frequency shift and latch-off function for two-level over-current protection (OCP), and an open-loop/over-load protection with an extended blanking time to limit the false trigger and in-rush current related damages. It is available in a surface-mount package that measures 4.8 x 5.8 mm and is ideal for LCD, PDP TV, AC-DC adapter, and audio SMPS applications.
