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.

Notes: 1.

All numeric values in the figure are typical values.
PFC-ON

The HA16141P/FP can perform on/off control of the PFC function using the PFC-ON pin.

If an AC voltage that has undergone primary rectification and has been divided with an external resistance is input,

PFC stoppage is possible in the event of a low input voltage.

On/off control by means of a logic signal is also possible.
PFC-FB

The input to this pin is the voltage obtained by dividing the stepped-up PFC output voltage.

The pin voltage is fed back to the PFC control system, and is also used for step-up voltage logic decisions.

This is outlined in the figure below.
