PFC and PWM Controller
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. The PFC power supply boosted output voltage is not only fed to an error amplifier input signal but also fed to as
the boost voltage monitor circuit. PG signal is put out if the boost voltage is out-of-spec.
The PWM controller, which begins operation at the same time as release of the IC’s UVLO (under-voltage lockout) is
suitable for auxiliary power supply use in a multi-output power supply system.
