Design files

Overview

PMP12003 is an isolated fly-buck-boost converter reference design with the primary side configured as an inverting buck-boost, using the LM5017 synchronous buck regulator IC. The design accepts an input voltage of 9Vin to 15Vin and provides an isolated output of 6.5Vout (+/-0.5V), capable of supplying 100mA of continuous current to the load. The nominal switching frequency of the design is 215KHz. This design is built on the PMP9291 Rev4 PCB, which is a 4-layer board with 1 oz. copper for the top and bottom layers and 0.5 oz. copper for the two inner layers.

Features
  • Primary-to-secondary isolation
  • Simple COT design requires no compensation
  • No need for optocoupler
  • Cycle-by-cycle current limit
