Semtech SC4901

Combi-Sync™ Secondary-Side Synchronous Rectifier and Regulator

Add to Watch List

Features


  • Single controller performs synchronous rectification and post regulation
  • Independent regulation of multiple outputs from a common secondary winding
  • Turn-on shoot-through inherently eliminated
  • Primary switch turns ON and OFF with zero current
  • No synchronizing or any other signals needed across the isolation boundary
  • Eliminates the need for a secondary bias supply
  • Independent soft start, ON/OFF, remote sense and current limit for each output
  • Resistive or inductive current sensing with 2 V current signal and 2.5 V reference for external applications
  • 4.5 V to 18 V operation
  • Max. operating frequency to 1 MHz
  • Low-profile 16-pin TSSOP package
  • Based on Semtech’s patent-pending Combi-Sync™ concept
