Analog Devices Inc./Maxim Integrated MAX18002WEVKIT#

Overview

MAX18002WEVKIT# from Analog Devices is a fully assembled and tested evaluation kit for the MAX18002AWT+ ultrasonic-mode boost converter in WLP package. It supports input voltage from 0.5V to 5.5V, delivers up to 3.6A inductor current, and enables output voltage adjustment from 2.5V to 5.5V in 100mV steps-ideal for validating low-noise power delivery in portable battery-powered systems.

For engineers reviewing the MAX18002WEVKIT# datasheet, MAX18002WEVKIT# pinout, MAX18002WEVKIT# application, or MAX18002WEVKIT# equivalent, this kit provides direct access to critical nodes (LX, OUT), configurable RSEL-based VOUT selection, jumper-controlled EN/SEL logic, and onboard test points for precise ripple, transient, and efficiency measurements under real load conditions.

Technical Context

The MAX18002WEVKIT# implements the full reference design for the MAX18002AWT+, including its 470nH power inductor (Murata DFE201612E-R47M), dual 22µF X5R 0603 input/output capacitors, and onboard SI4160DY N-channel MOSFET for optional integrated load testing. It replicates the IC's ultrasonic switching mode (FSW > 22kHz) behavior to eliminate audible noise during light-load operation.

Test points at INS/GNDS1 and OUTS/GNDS enable accurate measurement of input/output voltages at capacitor terminals-bypassing PCB trace drops-while miniature probe pads at LX and OUT support low-noise oscilloscope waveforms. Jumper JU1 (EN-to-VIN default) and JU2 (RSEL-to-potentiometer default) configure startup and output voltage without soldering.

FAQ

What does MAX18002WEVKIT# evaluate?

MAX18002WEVKIT# evaluates the MAX18002AWT+ ultrasonic-mode boost converter in WLP package. It is pre-populated with that specific IC and configured to demonstrate its full functionality-including 2.5V–5.5V adjustable output, 3.6A current capability, and FSW > 22kHz operation to avoid audible noise. The board also supports comparison with the nanopower MAX18000AWT+ variant via ordering option.

Does MAX18002WEVKIT# include the MAX18002 IC?

Yes, MAX18002WEVKIT# ships with the MAX18002AWT+ pre-soldered as U1. The label on the board identifies U1 as MAX18002AWT+, and the default jumper settings (JU1: 1–2, JU2: 1–2) configure it for immediate evaluation. No additional IC installation is required to begin testing input/output regulation, efficiency, or transient response.

How is output voltage set on MAX18002WEVKIT#?

Output voltage on MAX18002WEVKIT# is set using the RSEL pin. By default, JU2 connects RSEL to an onboard 1MΩ potentiometer (Bourns 3296Y-1-105LF), enabling continuous VOUT adjustment from 2.5V to 5.5V. Alternatively, a discrete resistor (e.g., 10.0kΩ for 5.0V) can be soldered in place of the potentiometer per Table 4 in the EV kit documentation.

Can MAX18002WEVKIT# be used to measure switching waveforms?

Yes, MAX18002WEVKIT# includes dedicated miniature probe pads at the LX and OUT nodes (compatible with Tektronix 131-4353-00 probes) to capture clean, low-noise switching waveforms. These pads minimize parasitic inductance and capacitance, enabling accurate measurement of ripple, rise/fall times, and load transients without probing directly on component leads or traces.

What load options does MAX18002WEVKIT# support?

MAX18002WEVKIT# supports both external and onboard loading. External loads connect via banana jacks (IN, OUT, GND). For integrated testing, the onboard SI4160DY N-channel MOSFET (Q1) can be enabled by soldering a connection between the OUT pad and Q1 pins 5–8; gate and source test points allow controlled FET biasing to simulate dynamic load steps without external equipment.
