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. 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.
