Description

The MAX17225 evaluation kit (EV kit) evaluates theMAX17220–MAX17225 IC family of ultra-low quiescent current step-up DC-DC converters. The MAX17225 EVkit features two independent circuits to evaluate two different IC packages of the MAX17220–MAX17225 family. Both circuits on the EV kit operate over an input range of 400mV to 5.5V, depending on load, with 0.88V typical startup with 3kΩ load. Each circuit provides resistor-configurable output voltages from 1.8V to 5V in 100mV/step.

Features

  • Two Independent Circuits on One Board
  • Evaluates the MAX17220–MAX17225 IC Family ina 6-pin μDFN
  • Evaluates the MAX17220–MAX17225 IC Family ina 6-pin Wafer-Level Package (WLP)
  • 400mV to 5.5V Input Range
  • 1.8V to 5V Configurable Output Voltage in100mV/step
  • Up to 100mA/225mA/425mA Output Current
  • Proven 2-Layer 1oz Copper PCB Layout
  • Demonstrates Compact Solution Size
  • Fully Assemble and Tested
