Preliminary

CMOS IC

3A, 1MHz, HIGH EFFICIENCY



DESCRIPTION

The UTC UD05303 is a high-efficiency 1MHz synchronous

step-down DC-DC regulator IC capable of delivering up to 3A

output current. The UTC UD05303 operates over a wide input

voltage ranging form 3~5.5V 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 provides the

system reset function and facilitates the output sequencing design.



FEATURES

* Low R_DS(ON)for internal switches (top/bottom) 100mΩ/70mΩ, 3A

* 3~5.5V input voltage range

* 1MHz switching frequency minimizes the external components

* Internal softstart limits the inrush current

*100% dropout operation

* Output power good indicator

* RoHS compliant and halogen free

* Compact and thermally enhanced SO8 package with exposed

paddle
