UD05203规格书详情
描述 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 to minimize the DS(ON)conduction loss. Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1MHz switching frequency.
特性 Features
Low RDS(ON) for internal switches (top/bottom) 130mΩ/100mΩ, 2A 3~5.5V input voltage range1MHz switching frequency minimizes the external componentsInternal softstart limits the inrush current100% dropout operation
