Semtech SC2449

Semtech SC2449

Bi-Phase/Dual Controller

Add to Watch List

The SC2449 can be configured as a dual converter or a bi-phase converter for high current applications. The part is designed for point of use power supplies with 8.5-28V nominal backplane power sources. Multiple supplies can be synchronized together to prevent low frequency harmonics on the backplane.

Features


  • Selectable dual-input or bi-phase operations
  • Direct drive for N-channel MOSFETs
  • Under-voltage lockout
  • Synchronization to external clock
  • Multi-converter synchronization
  • Soft start
  • Fast transient response
  • Max. duty cycle 45%
  • Output over-voltage protection
  • Thermal shutdown
  • 28-Pin SO lead free package available. Fully WEEE and RoHS compliant

Applications


  • Power supplies for advanced telecom/datacom
  • SO IP, Ethernet, and PABX power supllies

Packaging

SOIC-28-EDP
