Key Document


PMP9350 is a Constant On-Time synchronous buck regulator utilizing the LM5017 wide-vin with integrated HS and LS MOSFETs for industrial/automotive applications. This board was developed to fit into space-constrained applications. It also uses an external SS circuit for a reduced start-up time.

  • Synchronous rectifier for high efficiency
  • Temp rise of 20°C (IC)
  • 1” Sq solution size capable with integrated FETs
  • DCR ripple voltage injection to FB
  • Low component count
  • Adjustable switching frequency
