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 ...
