UD05021
2.0A 1.5MHZ SYNCHRONOUS
BUCK CONVERTER
 DESCRIPTION
The UTC UD05021 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.
