Typical Application

Description

SY21264A is a high efficiency, current-mode control Boost DC to DC regulator with an integrated 90mΩ  RDS(ON) N-channel MOSFET. The fixed 1MHz switching frequency and internal compensation reduce external component count and save the PCB space. The build-in internal soft start circuitry minimizes the inrush current at start-up.

Applications

  • 1-cell Li-ion Battery Powered Applications
  • Portable Devices
