Analog Devices Inc./Maxim Integrated MAX17225EVKIT#

Overview

MAX17225EVKIT# from Maxim Integrated is an evaluation kit designed to characterize the MAX17220–MAX17225 family of ultra-low quiescent current step-up DC-DC converters. It integrates two independent circuits - one with the MAX17225ELT+ (6-pin µDFN) configured for 3V output delivering up to 425mA at 1.8V input, and another with the MAX17225ENT+ (6-pin WLP) configured for 5V output delivering up to 425mA at 3V input - enabling comparative validation of package-dependent performance in energy-constrained applications.

For engineers reviewing the MAX17225EVKIT# datasheet, MAX17225EVKIT# pinout, MAX17225EVKIT# application, or MAX17225EVKIT# equivalent, this kit supports rapid functional verification of nano-power boost converter operation across 400mV–5.5V input, resistor-configurable 1.8V–5V outputs (100mV/step), dual-package evaluation, and battery-powered testing using CR1632 and silver-oxide coin cells.

Technical Context

The MAX17225EVKIT# implements two fully independent boost converter channels on a single 2-layer PCB: one based on the MAX17225ELT+ µDFN package with JU101 enable control and 3V output configuration, and the other on the MAX17225ENT+ WLP package with JU1 enable control and 5V output configuration. Each channel includes dedicated input terminals (IN/IN1), output terminals (3V/5V), ground posts (GND/GND1), and test points for LX switching node monitoring.

Both circuits support startup down to 400mV input (0.88V typical with 3kΩ load), use external 2.2µH inductors (L1/L101), and rely on resistor dividers (e.g., R101 = 133kΩ for 3V) to set output voltage. Spare components - including four 1206 resistors (768kΩ, 324kΩ, 133kΩ, 80.6kΩ) and five inductors (1µH to 2.2µH) - allow reconfiguration of output voltage and current capability without board modification.

FAQ

What is the purpose of the MAX17225EVKIT#?

The MAX17225EVKIT# is a fully assembled and tested evaluation platform for the MAX17220–MAX17225 family of ultra-low quiescent current step-up DC-DC converters. It enables engineers to validate performance of both the MAX17225ELT+ (µDFN6) and MAX17225ENT+ (WLP6) variants under real-world conditions - including low-voltage startup, configurable output regulation, and battery-powered operation - without custom PCB development. The MAX17225EVKIT# provides immediate access to proven layout, bill-of-materials, and test procedures.

Can the MAX17225EVKIT# evaluate other parts in the MAX17220–MAX17225 family?

Yes - the MAX17225EVKIT# is explicitly designed to evaluate any member of the MAX17220–MAX17225 family. The board accommodates replacement of U1 (WLP socket) and U101 (µDFN socket) with alternate ICs such as MAX17220, MAX17222, or MAX17224. Resistor and inductor spares allow output voltage and current reconfiguration to match each device's datasheet specifications, making the MAX17225EVKIT# a flexible tool across the entire family.

What are the default output configurations on the MAX17225EVKIT#?

The MAX17225EVKIT# ships with the MAX17225ELT+ (µDFN6) pre-installed and configured for 3V output using R101 = 133kΩ, and the MAX17225ENT+ (WLP6) pre-installed and configured for 5V output. Both channels operate over 400mV–5.5V input and deliver up to 425mA. Jumper settings JU101 (µDFN EN) and JU1 (WLP EN) are shipped in their default enabled positions, connecting EN to IN or IN1 through 33MΩ pull-up resistors.

Does the MAX17225EVKIT# support battery-powered testing?

Yes - the MAX17225EVKIT# includes two dedicated SMT battery holders: V1 accepts a CR1632 lithium coin cell to power the WLP circuit (5V channel), and V101 accepts an Energizer 364/363 silver oxide cell to power the µDFN circuit (3V channel). This enables true battery-source characterization - including cold-start behavior below 500mV - without external bench supplies, directly supporting design validation for long-life portable electronics using the MAX17225EVKIT#.

What spare components are included on the MAX17225EVKIT# for reconfiguration?

The MAX17225EVKIT# includes seven spare passive components on the bottom side: four 1206 resistors (768kΩ, 324kΩ, 133kΩ, 80.6kΩ) to reconfigure output voltage from 2.0V to 3.3V; and three inductors (1µH, 2.2µH variants) to adjust output current capability and optimize efficiency. These allow users to adapt the MAX17225EVKIT# to different MAX17220–MAX17225 variants or application-specific requirements without soldering new parts onto the top side.
