UD05203

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 R DS(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 R DS(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
