HA16158P Datasheet | Renesas

Description The HA16158 is a power supply controller IC bining 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.
