General Description

The AT1393 provides a complete power solution

for digital still and video cameras through the

integration of synchronous rectification topology ,

soft start function and short circuit detection

function. This IC is ideal for applications that use

either 2 or 3 alkaline or NIMH batteries as well as

those using a single Li-ion battery.

Applications

• Digital Cameras

• CCD Imaging Devices

• Camcorders
