Description

The PMP30197 reference design is an inverting Fly-BuckBoost power supply using the LM2743 to generate an isolated output voltage of 3.9V. The design accepts an input voltage of 2V to 5.25V.  The converter regulates the secondary side output with an optocoupler and is capable of achieving good output voltage regulation. The synchronous rectifier on the secondary output improves efficiency.

Features
  • Isolated output
  • Optocoupler regulated
  • Synchronous rectifier on the secondary winding improves efficiency
  • Test report available
