Analog Devices Inc./Maxim Integrated MAX18000WEVKIT#

Overview

MAX18000WEVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to demonstrate the MAX18000AWT+ nanopower boost converter in 1.56mm × 1.56mm WLP package. It supports input voltage from 0.5V to 5.5V, delivers up to 3.6A inductor current, enables output voltage adjustment from 2.5V to 5.5V in 100mV steps via RSEL resistor, and achieves 512nA quiescent current-ideal for ultra-low-power wearable and energy-harvesting applications.

For engineers reviewing the MAX18000WEVKIT# datasheet, MAX18000WEVKIT# pinout, MAX18000WEVKIT# application, or MAX18000WEVKIT# equivalent, this page provides verified hardware specifications, jumper configuration guidance, test point access details, output-voltage selection tables, and direct links to underlying IC performance characteristics including nanopower mode behavior and pass-through functionality.

Technical Context

The MAX18000WEVKIT# implements a complete reference design for the MAX18000AWT+, featuring a 470nH shielded inductor (DFE201612E-R47M), dual 22µF X5R 0603 input/output ceramic capacitors, and onboard test points for INS, OUTS, GNDS, LX, and OUT. Critical nodes support Tektronix miniature probe insertion (131-4353-00) for low-noise ripple and transient waveform measurement.

Jumper JU1 (EN control) defaults to 1–2 (EN tied to VIN), and JU2 (RSEL interface) defaults to 1–2 (RSEL connected to on-board potentiometer). The board includes an optional onboard N-channel MOSFET (SI4160DY-T1-GE3) for load testing, with drain connection enabled via solder bridge per Figure 6.

FAQ

What IC does the MAX18000WEVKIT# evaluate?

The MAX18000WEVKIT# evaluates the MAX18000AWT+, a nanopower synchronous boost converter in a 1.56mm × 1.56mm WLP package. It is preinstalled as U1 on the board and labeled accordingly. The kit is not interchangeable with MAX18002AWT+ without verifying jumper settings and RSEL configuration, as the two ICs differ in operating mode (nanopower vs. ultrasonic) and quiescent current behavior.

Does the MAX18000WEVKIT# support adjustable output voltage?

Yes, the MAX18000WEVKIT# supports output voltage adjustment from 2.5V to 5.5V in precise 100mV increments using an external resistor connected to the RSEL pin. Table 4 in the documentation lists exact RSEL values (e.g., 768kΩ for 2.5V, 10.0kΩ for 5.0V). Jumper JU2 must be set to 1–2 to route RSEL to the onboard potentiometer or external resistor network.

What is the measured quiescent current of the MAX18000WEVKIT#?

The MAX18000WEVKIT# measures 25µA input current under no-load conditions when evaluating the MAX18000AWT+, as confirmed in Table 3 of the EV kit documentation. This reflects the ultra-low 512nA quiescent current of the MAX18000AWT+ IC itself, scaled by board-level bias and measurement setup, making it suitable for decade-scale battery operation in maintenance-free devices.

How do I configure the MAX18000WEVKIT# for initial power-up?

Set jumper JU1 to positions 1–2 (EN tied to VIN) and JU2 to positions 1–2 (RSEL connected to potentiometer). Connect a 3.6V/100mA-limited DC source to IN and GND. Measure output with DVM across OUTS and GNDS - expect ~5.14V with RSEL set to 10kΩ. Confirm startup by observing stable regulation before increasing load or adjusting RSEL.

Can the MAX18000WEVKIT# be used to evaluate switching waveforms?

Yes, the MAX18000WEVKIT# includes dedicated probing holes at LX and OUT nodes compatible with Tektronix miniature probes (131-4353-00). These enable low-noise, high-fidelity capture of switching waveforms, output voltage ripple, and load transient response - critical for validating EMI compliance and efficiency in nanopower boost designs using the MAX18000AWT+.
