Minature 2A Power Supply with LMZ20502 Nano Module - Reference Design


Design files


The PMP10595 reference design is a miniature 1.8V, 2A output power supply using the SIMPLE SWITCHER® LMZ20502 nano module. The reference design takes advantage of the miniature package and high level integration of the LMZ20502 to achieve small solution size, which is about 5mm x 6mm (30 sq. mm). The design can supply up to 2A output from an input range of 2.7V to 5.5V. On the reference board the LMZ20502 is set in AUTO mode, and it can achieve good efficiency from light to full load.

  • LMZ20502 nano module with integrated inductor
  • 2.7V to 5.5V input, 1.8V, 2A output power supply
  • 30 sq. mm tiny solution size
  • Sub 100uA operating quiescent current
  • Good light load efficiency with LMZ20502's AUTO mode
  • This circuit board is tested, and the design files and test report are included.
