High-Performance Synchronous Buck Controller with Reference Tracking

加入关注列表

The SC4510 can be configured as a synchronous buck convertor capable of sourcing and sinking current from load without losing output regulation.

Features


  • Synchronous buck operation with current sink or source without loss of regulation
  • Output can track internal or external reference
  • Buffered reference output from external reference
  • Combi-Sense™ mode lossless current sensing
  • 2.5 V to 16 V operation with 4.75 V minimum VCC
  • Direct drive for high-side N-channel MOSFETs with diode and capacitor bootstrap
  • Under-voltage lockout, soft start, enable, power-good functions
  • Fast transient response with external compensation
  • Current-mode control with transductance error amplifier
  • Programmable oscillator frequency with external sync
  • Thermal shutdown
  • Space-saving TSSOP-20 package
