PMP20330 is an isolated Flybuck converter utilizing the LM5160 for industrial applications. This design has a minimum operating input voltage of 18V and a maximum input voltage of 31V. The design is capable of sourcing 1A continuous current at 3.3Vout, and 0.5A continuous current at 5Vout. Switching frequency is set to 200kHz. A Wurth transformer 750316561 is used for this design.
Features
