Description

The SC250 is an ultra high efficiency .2A DC/DC buck

regulator available in a tiny CSP package. These features

make the SC250 family perfect for small form factor

portable applications where long battery life is essential.

SC250 is an Adaptive On-Time 4MHz switching regula-

tor at full load conditions. Under light load conditions it

seamlessly transitions into Power Save Mode and reduces

switching frequency thus saving energy. High switching

frequency operation allows the use of a very small 0.47μH

inductor along with small input and output capacitors to

minimize overall circuit size. A Forced PWM input allows

continuous switching under all load conditions.

The SC250 is highly configurable with a wide range of

factory options including internal Soft Start time, fixed or

adjustable output voltage, automatic output discharge,

and a Forced PWM input.

The SC250 is offered in an ultra small WLCSP 6-Bump

0.75mm x.mm package with a bump pitch of 0.35mm.

The SC250 operating temperature range is -40C to

+85C.
