200W SMPS EVA Board

The demoboard described in this paper is a 200W half bridge LLC resonant converter using LLC controller ICE1HS01G/-1, which is a 8-pin LLC controller developed by Infineon Technologies. ICE1HS01G/-1 is specially designed for applications of switch mode power supplies used in LCD / PDP TV, AC/DC adapter and Audio system. ICE1HS01G/-1 is a 8-pin controller IC in DSO package and it is very flexible to implement in the PCB. Furthermore, it includes all the necessary control strategies for HB LLC resonant converter. ICE1HS01G/-1 allows the designer to select suitable operation frequency range by programming the oscillator with an external resistor. The built-in soft-start function is available to limit both the inrush current and the overshoot of output voltage. In addition, ICE1HS01G/-1 can perform all the necessary protection functions in HB LLC resonant converters. All those functions make ICE1HS01G/-1 an outstanding product for HB LLC resonant converter in the market
