Description

The PMP10100 reference design uses the LM5023 flyback controller for the Quasi-Resonant Flyback Topology. It generates an isolated output (19.5V@3.84A) from an universal input (85VAC - 265VAC).

Features
  • Quasi-Resonant Flyback Topology
  • Four Point Average Efficiency = 89.3% (Vin=110VAC)
  • Four Point Average Efficiency = 89.4% (Vin=230VAC)
  • 10% Load Efficiency = 89.6% (Vin=110VAC)
  • 10% Load Efficiency = 87.2% (Vin=230VAC)
