Semtech SC191

Low Supply Ripple Synchronous Buck Conversion Regulator

Add to Watch List

The SC191 is a synchronous step-down converter with integrated power devices and an integrated front-end LDO regulator to minimize input supply ripple. If supply ripple is not a concern, the front-end LDO regulator can be bypassed externally to maximize efficiency.

  • Less than 1mV Supply Ripple
  • 2.7V to 5.5V Input Range
  • 330mA Guaranteed Output Current
  • Fixed Frequency 1MHz Operation
  • No Schottky Diode Required
  • Over-Current Protection
  • Over-Voltage Protection
  • Over-Temperature Protection
  • Soft-Start
  • No External Compensation Required
  • MLPD-8, 2.3mm x 2.3mm Package
