Infineon Technologies ICE1HS01G-1 | Demoboard AN-EVAL-1HS01G-1-200W

Description

The demo board described in this paper is a 200W half bridge LLC resonant converter using LLC controller ICE1HS01G-1, which is an 8-pin LLC controller developed by Infineon Technologies. ICE1HS01G-1 is speciallydesigned for applications of switch mode power supplies used in LED / OLED / LCD / PDP TV, AC/DC adapter and Audio system.ICE1HS01G-1 is an 8-pin DSO-8 controller IC, the PCB layout can be easily implemented. Moreover, it includes all necessary control strategies for HB LLC resonant converter. ICE1HS01G-1 allows the designer tochoose suitable operation frequency range by programming the oscillator with an external resistor. And the built-in soft-start function to limit both the inrush current and the overshoot of output voltage is also provided. In addition, ICE1HS01G-1 performs all necessary protection functions in HB LLC resonantconverters. All of these make ICE1HS01G-1 an outstanding product for HB LLC resonant converter in the market.
