DESCRIPTION

The A7632 is a constant frequency, current mode

step-up converter intended for small, low power

applications.

The A7632 switches at 1.2MHz and allows the use of

tiny, low cost capacitors and inductors 2mm or less in

height. Internal soft-start results in small inrush

current and extends battery life.

The A7632 includes under-voltage lockout, current

limiting, and thermal overload protection to prevent

damage in the event of an output overload.

The A7632 is available in SOT-26 package.
