Description

PMP9403 is a high-efficiency dual-phase synchronous boost converter using the LM5122 controller ICs. The design accepts an input voltage of 9Vin to 15Vin (12Vin Nominal) and provides an output of 48Vout capable of supplying 4A of continuous current to the load.

Features
  • Synchronous rectification for high efficiency
  • High power density
  • Interleaved multi-phase with current sharing
  • Low temperature rise
  • Hiccup-mode overload protection
  • Precision voltage reference accuracy of +/-1%
