SY8081小封装降压5V低电压DC/DC调节器SILERGY一级代理
税前: ¥1.50
General Description
SY8081 is a high efficiency 2.5MHz synchronous step down DC/DC regulator IC capable of delivering up to 1A output currents. It can operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS (ON)to minimize the conduction loss. Features
Low RDS(ON)for internal switches (top/bottom) 230mΩ/150mΩ
2.5~5.5V input voltage range
High switching frequency 2.5MHz minimizes the external components
Internal soft-start limits the inrush current
100% dropout operation
RoHS Compliant and Halogen Free
Output auto discharge function
Compact package: DFN1.5x1.5-6
Applications
Portable Navigation Device
Set Top Box
USB Dongle
Media Player
Smart phone
