CMOS IC

2.0A 1.5MHZ SYNCHRONOUS

BUCK CONVERTER



DESCRIPTION

The UTC UD05205 is a monolithic synchronous buck regulator

with a built in internal power MOSFET. It achieves 2A continuous

output current fix switching frequency with excellent load and line

regulation.

Current mode operation provides fast transient response and

eases of loop stabilization.

Fault condition protection includes cycle-by-cycle current limiting,

output short circuit protection and thermal shutdown. In shutdown

mode the regulator draws less than 1μA of supply current. Internal

soft-start minimizes the inrush supply current at initial startup.


