Description

The PMP10638 reference design is a -5.2V 4A output power supply using SIMPLE SWITCHER® LMZ31710 Power Module. The reference design takes advantage of the small package and high level integration of LMZ31710 to achieve small solution size. It can support -5.2V 4A output power from 3.1V-3.3V input range. The working frequency is set to 1Mhz and very small ripple voltage.

Features
  • LMZ3710 power module with integrated inductor
  • 3.1V to 3.5V input , -5.2V 4A output
  • Less than 15 components
  • 1Mhz working frequency, 88% peak efficiency
  • This circuit board is tested, and the design files and test report are included
