Description

PMP11422 is a synchronous boost power supply using the LM5121 controllers. The design accepts an input voltage of 5Vin to 8.6Vin, and boosts a 12Vout rail capable of sourcing 6A continuous current. The LM5121 integrates an input disconnection switch feature which allows boost short circuit protection, the device turns off the switch when a short circuit event occurs.

Features
  • High density design
  • Integrated boost short circuit protection
  • 72W capability
  • +/- 5% load transient
  • Overvoltage, and overcurrent protection
