UD05303
Preliminary
3A, 1MHz, HIGH EFFICIENCY
CMOS IC
ï® 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 RDS(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.
ï® FEATURES
* Low RDS(ON) for internal switches (top/bottom) 100mâ¦/70mâ¦, 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
