HIGH EFFICIENCY 1MHZ, DUAL 3A SYNCHRONOUS STEP DOWN REGULATOR
DESCRIPTION
The UTC UD05302 is a high-efficiency 1MHz synchronous
step-down DC-DC regulator IC capable of delivering up to 3A
output current. The UTC UD05302 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 R for internal switches (top/bottom) 110m/80m DS(ON)
* 3~5.5V input voltage range
* 1MHz switching frequency minimizes the external components
* Internal softstart limits the inrush current
* 100% dropout operation |
