protection circuit (SCP).

General Description

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 fly-back conversion.

Applications

„ LCD Displays

„ PDAs

„ Digital Still Cameras
