Analog Devices Inc./Maxim Integrated MAX17250EVKIT#

Overview

The MAX17250EVKIT# from Maxim Integrated is an evaluation kit for the MAX17250 synchronous boost converter IC, designed to accelerate development of high-efficiency, ultra-low-quiescent-current DC-DC step-up power supplies. It supports input voltages from 2.7V to 18V and programmable output voltages from 3V to 18V, features True Shutdown™ with 0.1μA shutdown current, selectable input peak current limits (1.85A/2.7A/3.5A), and short-circuit protection - enabling rapid prototyping for battery-powered IoT sensors and display bias supplies.

For engineers reviewing the MAX17250EVKIT# datasheet, MAX17250EVKIT# pinout, MAX17250EVKIT# application, or MAX17250EVKIT# equivalent, this kit provides validated reference design, thermal performance data, layout guidelines, and full test points for evaluating MAX17250-based boost converters in space-constrained, low-power embedded systems requiring stable 3–18V rail generation from single/dual Li-ion cells.

Technical Context

The MAX17250EVKIT# implements the MAX17250's fixed on-time / minimum off-time PFM control architecture, supporting CCM and DCM operation across load currents from 100µA to 760mA. It validates the IC's 800ns maximum on-time, 200ns minimum off-time, and three ISET-configurable peak current limits (1.85A/2.7A/3.5A) under real PCB thermal conditions using either the 12-bump WLP or 14-pin TDFN package variants.

This kit integrates all critical passive components per Maxim's recommended design: dual 10µF X5R/X7R input capacitors, 10µF output capacitor, two 22µF PVH decoupling capacitors, 0.1µF BST capacitor, 2.2µF VL capacitor, and a 2.2µH shielded inductor - enabling immediate functional validation without component selection overhead.

FAQ

What does the MAX17250EVKIT# evaluate?

The MAX17250EVKIT# evaluates the MAX17250 synchronous boost converter IC, including its True Shutdown™ functionality, selectable input peak current limits (1.85A/2.7A/3.5A), 2.7V–18V input range, 3V–18V output capability, and thermal performance in both 12-bump WLP and 14-pin TDFN packages. It provides fully assembled, tested hardware with documented test points and layout files for immediate validation of MAX17250-based designs.

Does the MAX17250EVKIT# support both WLP and TDFN package variants of the MAX17250?

Yes, the MAX17250EVKIT# supports both the MAX17250ANC+ (12-bump WLP) and MAX17250ATD+ (14-pin TDFN) variants. The evaluation board includes footprint compatibility and layout provisions for either package, with thermal vias and copper pours optimized per package-specific θJA values (72.82°C/W for WLP, 41°C/W for TDFN on four-layer board).

What are the key passive components pre-installed on the MAX17250EVKIT#?

The MAX17250EVKIT# includes all critical passives per Maxim's recommended design: dual 10µF X7R input capacitors, 10µF X7R output capacitor, two 22µF X7R PVH capacitors, 0.1µF BST capacitor, 2.2µF X5R VL capacitor, and a 2.2µH shielded inductor. These components enable immediate functional testing without external component selection or placement.

How is True Shutdown™ validated on the MAX17250EVKIT#?

True Shutdown™ is validated on the MAX17250EVKIT# by measuring shutdown current at the input rail with EN = 0V, confirming <0.001µA (typical 0.1µA) drain - consistent with MAX17250 datasheet specifications. The kit also demonstrates complete input-output isolation during shutdown, preventing reverse current flow and enabling true zero-load battery drain in always-on IoT endpoints.

Can the MAX17250EVKIT# be used to evaluate efficiency and thermal performance?

Yes, the MAX17250EVKIT# enables direct measurement of efficiency (via input/output voltage/current test points) and thermal performance (using onboard temperature monitoring and validated θJA/θJC data). Typical efficiency curves (e.g., 93% at 125mA, 75–90% across 1mA–760mA loads) and junction temperature rise (e.g., +22°C above ambient at 0.76A with WLP) are documented in the MAX17250 datasheet and reproducible using this kit.
