Design files

Overview

The PMP20070 reference design is a boost converter designed for high pulse current applications. It delivers 65V output at 420mA average, from a nominal input voltage of either 12V or 24V. This design uses the LM5022 boost controller at a switching frequency of 650 kHz. A resistor and P-channel MOSFET load switch is used to limit the startup current. Pulse load characterization was done at 30A for 2.5 ms.

Features
  • 27W continuous output power
  • 30A 2.5ms peak output current
  • Load switch limits startup current
  • 2 layer board
  • Synchronizable to external clock
