AT1380A Datasheet (Aimtron Technology) - Switching Regulator Controller

AT1380A, Switching Regulator Controller

The AT1380A is a single-channel PWM control IC for DC/DC conversion with soft start function and short circuit detection.

Adjustable soft start is programmed with an external capacitor on SCP pin.

The AT1380A is ideal for up, down and flyback conversion.
