UD05303规格书详情
描述 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 ) to minimize the synchronous switch with very low RDS(ONconduction 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.
特性 Features
• Low RDS(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
