APW7066 Datasheet PDF - Anpec Electronics

General Description
The APW7066 has two synchronous buck PWM control lers and one linear controller with high precision internal references voltage to offer accurate outputs. The PWM controllers are designed to drive two N-channel MOSFETs in synchronous buck topology, and the linear controller drives an external N-channel MOSFET. The device requires 12V and 5V power supplies, if the 5V supply is not available, VCC12 can offer an optional shunt regulator 5.8V for 5V supply.
