HA16158P/FP
PFC & PWM Control IC
ADE-204-072 (Z)
Rev.0
Aug. 2002
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 dewcrewaswin.gDsawtiatcShihneg elots4sU. .com
The PFC section and PWM section are each provided with a soft start control pin, enabling a soft start time
to be set easily.
