HA16158P/FP
PFC & PWM Control IC
REJ03F0147-0200

Description
The HA16158 is a power supply controller IC combining an AC-DC converter switching controller for power factor
correction and an off-line power supply switching controller. The PFC (power factor correction) section employs
average current mode PWM and the off-line power supply control section employs peak current mode PWM.
The HA16158 allows the operating frequency to be varied with a single timing resistance, enabling it to be used for a
variety of applications.
The PFC operation can be turned on and off by an 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 PWM controller includes a power-saving function that reduces the operating frequency to a maximum of 1/64 in
the standby state, greatly decreasing switching loss.
The PFC section and PWM section are each provided with a soft start control pin, enabling a soft start time to be set
easily.
