Description

PMP7979 is a synchronous dual-phase boost power supply using the LM5122 controllers. The design accepts an input voltage of 12 V to 67 V, and boosts a 54-V output rail that is capable of sourcing 4.8-A continuous current. The LM5122 has an internal current source to keep the high-side FET to run at 100% duty cycle, which allows a bypass operation when the input voltage is greater than the configured output voltage.

Features
  • 12 Vin to 67 Vin, 54 Vout at 5-A out; IC capable of 4.5 Vin to 65 Vin
  • 260-W Pout
  • Peak efficiency at 98%
  • Switching frequency 100 kHz per phase (200 kHz)
  • Board size: 4 in x 3 in
