HA16158P 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...
