HA16141P/FP, HA16142P/FP PFC and PWM Controller ADE-204-036D (Z) Preliminary Rev. 4 Sep. 2001 Description 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 section employs peak current mode PWM. The HA16142P/FP is the change version of HA16141P/FP’s PWM maximum on duty cycle. The PFC operation can be turned on and off by external control signal. Use of this on/off function makes it possible to disable PFC operation at a low line voltage, or to perform remote control operation from the transformer secondary side.
