Hs8108 is a PWM switching power supply control IC, which is mainly used for the switching power supply of desktop PC (personal computer).

Hs8108b can provide all control and protection functions of PC power supply: PWM pulse width modulation and push-pull output, with protection functions such as overvoltage, undervoltage, overcurrent, overload, AC undervoltage, etc.With accurate timing and few external devices, it is the best choice for the new generation of high-performance ATX power supply.
