24Vin, 5V6A Power Module Reference Design


Design files


PMP40274 is a power module reference design solution for power train applications. The module enables a high efficiency with flyback-CCM synchronous rectifier. The efficiency is >88% at full load. This design features <0.2W standby power. Integrated input UVLO, OVP and output OVP, OCP improves the power system reliability. The design is achieved in a compact form factor (50.8mm X 40.6mm X 15mm).

  • Synchronous rectifier flyback topology
  • Lower standby power
  • Input UVLO, OVP, output OVP
  • Output overcurrent protection with automatic retry
  • Size L*W*H 50.8mm*40.6mm*15mm
