PMP21055

Design files

Overview

The PMP21055 reference design converts a 0.8V to 4.2V input to a 3.3V/100mA output in a small form factor measuring 12mmx8mm. The design is built on a 2 layer, 1oz board and is a low-cost, small size design intended for battery powered applications. 

Features
  • 0.8V-4.2Vdc input to 3.3V/100mA output
  • >85% efficiency at 3Vin, 100mA load
  • Boost+buck design for low Vin operation
  • Complete test report and design support collateral, including thermal performance
  • 1oz, 2-layer board, 12mm x 8mm solution size
