HIGH EFFICIENCY 1MHZ, 2A

SYNCHRONOUS STEP DOWN

REGULATOR



DESCRIPTION

The UTC UD05203 is a high-efficiency 1MHz synchronous

step-down DC-DC regulator IC capable of delivering up to 2A

output current. The UTC UD05203 operates over a wide input

voltage ranging from 3V to 5.5V and integrate main switch and

synchronous switch with very low RDS(ON) to minimize the

conduction loss.

Low output voltage ripple and small external inductor and

capacitor sizes are achieved with 1MHz switching frequency.



FEATURES

* Low RDS(ON) for internal switches (top/bottom) 130mΩ/100mΩ, 2A

* 3~5.5V input voltage range

* 1MHz switching frequency minimizes the external components

* Internal softstart limits the inrush current

* 100% dropout operation
