Description

PMP9372 is a single-phase synchronous boost converter, which utilizes the LM5121 controller. Inrush limiting is set to 11A nominal, which allows startup into a 4700μF output capacitor. The TPS3700DDC is used as an output voltage monitor, which provides Power Good signaling of output over-voltage and under-voltage.

Features
  • Single Phase Synchronous Boost Converter
  • 60W Pout
  • Efficiency 97% at 12V Input
  • Input Over Current Disconnect through Series Switch
  • Switching frequency 450kHz
  • 6 Layer Board
