Project Introduction

The power module designed based on EA3036.The EA3036 is a 3CH buck power meanagement ic.The module can be used for multiple power supply applications.

Features

  • 2.7V to 5.5V input voltag range
  • 0.6V to Vin output voltage range
  • Maximum Continuous Load Current: 2A (3CH total output power consumption must be less than 6W)
  • For more features, please refer to the EA3036 datasheet

Project SCH

  • Default parameter: 3.3V output for all three channels
  • Change the output voltage by adjusting R1/R2, R4/R3, and R6/R5
  • The C2、C5 and C8 is feedback loop regulation capacitor

Project PCB

  • PCB design is compatible with DIP-2.54MM and Snap off hol
  • Using Snap off hol design requires changing the top layer silk screen at the solder pad to a borde
