Analog Devices Inc./Maxim Integrated MAX17291BEVK#WLP

Overview

MAX17291BEVK#WLP from Maxim Integrated is an evaluation kit designed to validate the MAX17291B high-voltage micropower boost DC-DC converter in 6-bump WLP (0.4mm pitch, 3×2 bump array). It supports 1.8V–4.5V input, delivers up to 50mA at 12V output, and features True Shutdown™, short-circuit protection, and resistor-configurable 5.5V–20V output voltage.

For engineers reviewing the MAX17291BEVK#WLP datasheet, MAX17291BEVK#WLP pinout, MAX17291BEVK#WLP application, or MAX17291BEVK#WLP equivalent, this EV kit enables rapid functional verification, efficiency measurement, shutdown behavior validation, and layout reference for space-constrained portable power designs using the MAX17291B IC.

Technical Context

The MAX17291BEVK#WLP implements a complete, fully assembled test platform for the MAX17291B step-up converter, configured with R1/R2 to set a nominal 12V output. It integrates a 10µH shielded inductor (DFE201610E-100M), 10µF/10V input ceramic capacitors (0805), and a 150µF/6.3V aluminum electrolytic output capacitor (UWJ0J151MCL) to support stable operation across the full 1.8V–4.5V input range.

Jumper JU1 provides hardware enable/disable control of the MAX17291B via EN pin, with shunt position 1–2 as default enabled state (EN = IN). Test points (TP2–TP4, EN, LX) and banana jacks (IN, OUT, PGND, PGND2) allow direct probing and load connection without soldering.

FAQ

What is the primary function of the MAX17291BEVK#WLP evaluation kit?

The MAX17291BEVK#WLP evaluation kit is a fully assembled and tested hardware platform that validates the electrical performance and application behavior of the MAX17291B high-voltage micropower boost converter. It enables engineers to measure efficiency, verify True Shutdown™ operation, characterize output regulation under varying loads, and assess PCB layout suitability before integrating the MAX17291BANT+ into their own designs.

Does the MAX17291BEVK#WLP support adjustable output voltage, and how is it configured?

Yes, the MAX17291BEVK#WLP supports resistor-configurable output voltage from 5.5V to 20V, per the MAX17291B's feedback divider architecture. It ships preconfigured with R1 (3.48MΩ) and R2 (402kΩ) to deliver 12V. Users can replace these 0603 resistors to scale the output voltage using the formula V_OUT = 1.215V × (1 + R1/R2), maintaining stability with the provided 10µH inductor and 150µF output capacitor.

What input power requirements must be met to operate the MAX17291BEVK#WLP?

The MAX17291BEVK#WLP requires a stable 1.8V–4.5V DC power supply capable of delivering ≥5A peak current. The kit draws minimal quiescent current when disabled (True Shutdown™ active), but during operation-especially at 12V/50mA output-it demands sufficient input current headroom to sustain the boost conversion ratio. A lab-grade supply with overcurrent protection is recommended for safe evaluation.

How is enable/disable control implemented on the MAX17291BEVK#WLP?

Enable/disable control is implemented via jumper JU1: shunt position 1–2 connects EN to IN (default enabled), while position 2–3 pulls EN to GND (disabled). This directly controls the MAX17291B's EN pin, activating True Shutdown™ in the disabled state-fully isolating output from input with no leakage current. No external logic or microcontroller is needed for basic functional testing.

What components are included on the MAX17291BEVK#WLP board for signal probing and load connection?

The MAX17291BEVK#WLP includes dedicated test points (TP2, TP3, TP4, EN, LX) with 0.125″ pin diameter for oscilloscope probes, plus four banana jacks (IN, OUT, PGND, PGND2) rated for secure load and supply connections. These interfaces eliminate soldering requirements and allow real-time monitoring of input/output voltages, enable status, and switch-node (LX) waveforms during transient and steady-state operation of the MAX17291B.
