Semtech SC2450

Bi-Phase/Dual Controller

The SC2450 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 8.5-30V nominal backplane power sources. Multiple supplies can be synchronized together to prevent low frequency harmonics on the backplane.

Features

  • Selectable dual-output or bi-phase operation
  • 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 supplies
