SY8881 - 1A Synchronous Step Down Regulator

General Description

SY8881 is a high efficiency 2.5MHz synchronous step down DC/DC regulator IC capable of delivering up to 1A output currents.

switch and synchronous switch with very low RDS (ON) to minimize the conduction loss.

Key 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 Hal gen Free.
  • Output auto discharge function.
  • Compact package: DFN1.5x1.5-6.
