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 to minimize the
DS(ON)
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
