Analog Devices Inc./Maxim Integrated MAX17227JEVK#WLP

Overview

MAX17227JEVK#WLP from Analog Devices is a fully assembled and tested evaluation kit designed to characterize the MAX17227J nanoPower boost converter in 6-pin WLP package. It supports input voltages from 400mV to 5.5V, features jumper-configurable output voltages (2.3V–5.4V), delivers up to 300mA at 5.0V (VIN > 3.6V), and demonstrates automatic pass-through operation when VIN exceeds VOUT - ideal for ultra-low-power energy harvesting and battery-backed sensor nodes.

For engineers reviewing the MAX17227JEVK#WLP datasheet, MAX17227JEVK#WLP pinout, MAX17227JEVK#WLP application, or MAX17227JEVK#WLP equivalent, this EV kit enables rapid validation of startup behavior (880mV min), load regulation, pass-through transition, and resistor-based output voltage configuration without custom PCB design.

Technical Context

The MAX17227JEVK#WLP implements a complete reference design for the MAX17227J IC, including its 6-pin WLP footprint, integrated 2.2µH power inductor (Würth 74479276222), dual 10µF ceramic input/output capacitors, and precision feedback resistors (R2–R5) enabling five discrete output settings via JU2 jumper. The board uses a proven 2-layer, 1oz copper layout optimized for low-noise nanoPower operation.

Hardware-level control is provided through two key jumpers: JU1 (EN enable/disable with TTL-compatible logic) and JU2 (5-position output voltage selection). The kit ships with MAX17227JANT+ pre-installed and includes banana jack terminals (Emerson 108-0740-001) for IN, OUT, and GND connections, plus test points for EN and RSEL signals.

FAQ

What is the primary function of the MAX17227JEVK#WLP?

The MAX17227JEVK#WLP is an evaluation kit that enables hardware validation of the MAX17227J nanoPower boost converter. It provides immediate access to all critical operating modes - including startup at 880mV, regulated boost operation, and automatic pass-through when VIN > VOUT - using factory-tested components and a production-ready PCB layout. The MAX17227JEVK#WLP requires no soldering or configuration beyond jumper selection.

Does the MAX17227JEVK#WLP include the MAX17227J IC?

Yes, the MAX17227JEVK#WLP ships with the MAX17227JANT+ pre-soldered and fully functional. This variant is the same MAX17227J device in a 6-pin WLP package (package code N60O1+1), qualified for operation across the full 400mV–5.5V input range and featuring 500mA peak inductor current limiting. The MAX17227JEVK#WLP's schematic and layout are optimized specifically for this IC.

How do I configure the output voltage on the MAX17227JEVK#WLP?

Output voltage is selected using jumper JU2: positions 1–2 = 2.5V, 1–3 = 3.0V, 1–4 = 4.0V, and 1–5 = 5.0V (default). For voltages between 2.3V and 5.4V outside these presets, remove the JU2 shunt and install a resistor at R1 per the MAX17227J datasheet's RSEL selection table. The MAX17227JEVK#WLP's BOM and schematic confirm R1 is DNP by default, supporting both methods.

Can the MAX17227JEVK#WLP operate with input voltages below 1V?

Yes - the MAX17227JEVK#WLP supports inputs as low as 400mV and starts regulating at 880mV typical with a 3kΩ load. This capability is enabled by the underlying MAX17227J's proprietary nanoPower architecture and verified on the EV kit's 2-layer PCB. Operation below 1V is stable and repeatable, making the MAX17227JEVK#WLP suitable for thermoelectric or photovoltaic energy harvesting evaluation.

Is the MAX17227JEVK#WLP RoHS compliant?

Yes, the MAX17227JEVK#WLP is RoHS compliant, as indicated by the "#" symbol in its part number per Analog Devices' ordering nomenclature. All components listed in the official BOM - including Murata GRM188Z71A106KA73 capacitors, Würth 74479276222 inductor, and Vishay/Panasonic resistors - meet RoHS Directive 2011/65/EU requirements.
