HA16141P Datasheet (Hitachi Semiconductor)

HA16141P, PFC and PWM Controller

The HA16141P/FP and the HA16142P/FP are power supply controller ICs combining an AC-DC converter switching controllers for power factor correction and off-line power supply switching controllers.

PFC (Power factor correction) section employs average current mode PWM and off-line power supply control
