Semtech SC419

Single Phase DC-DC Converter with Integrated Boost Diode

加入关注列表

The SC419 is a synchronous buck power supply controller. It features a bootstrap switch in a space-saving MLPQ- 3x3mm 20-pin package. The device is highly effi cient and uses minimal PCB area. It uses pseudo-fi xed frequency adaptive on-time operation to provide fast transient response.

Features


  • Input voltage — 3V to 28V
  • Integrated bootstrap switch
  • Smart power-save protection
  • TC compensated RDS(ON)
  • Pseudo-fi xed frequency adaptive on-time control
  • Designed for use with ceramic capacitors
  • Programmable VIN UVLO threshold
  • Enable input
  • Selectable power-save mode
  • Programmable ultra-sonic power-save
  • Internal soft-start and soft-shutdown at output
  • Internal reference — 1% tolerance
  • Over-voltage/under-voltage fault protection
  • Power good output
  • SmartDrive™
  • Lead-free 3x3mm, 20-Pin MLPQ package
  • Fully WEEE and RoHS compliant
