Analog Devices Inc./Maxim Integrated MAX17227JEVK#TDFN

Overview

MAX17227JEVK#TDFN from Analog Devices is an evaluation kit designed to validate the MAX17227J nanoPower boost converter in 8-pin TDFN package, supporting input voltages from 400mV to 5.5V, configurable output voltages from 2.3V to 5.4V, and up to 300mA output current at 5.0V with VIN > 3.6V - used for ultra-low-power battery-powered sensor nodes and energy-harvesting systems.

For engineers reviewing the MAX17227JEVK#TDFN datasheet, MAX17227JEVK#TDFN pinout, MAX17227JEVK#TDFN application, or MAX17227JEVK#TDFN equivalent, this EV kit provides a fully assembled, tested, and resistor-configurable platform to verify startup behavior (0.88V typical with 3kΩ load), automatic pass-through mode, and compact 2-layer PCB implementation before system integration.

Technical Context

The MAX17227JEVK#TDFN implements the MAX17227J IC - a synchronous nanoPower boost converter featuring automatic pass-through operation when VIN exceeds VOUT, enabling seamless transition between boost and direct conduction modes without external control logic.

Hardware-level configuration is achieved via two shunt jumpers: JU1 (EN enable/disable) defaults to pins 1–2 for active operation, and JU2 (output voltage selection) defaults to pins 1–5 for 5.0V output, with four discrete resistor-based settings covering 2.5V, 3.0V, 4.0V, and 5.0V.

FAQ

What is the primary function of the MAX17227JEVK#TDFN?

The MAX17227JEVK#TDFN is a fully assembled evaluation kit that demonstrates and validates the operation of the MAX17227J nanoPower boost converter IC. It enables engineers to verify startup behavior, output regulation, automatic pass-through mode, and efficiency across its 400mV–5.5V input range without designing custom hardware. The MAX17227JEVK#TDFN includes pre-installed MAX17227JATA+ and configurable jumpers for immediate bench testing.

Does the MAX17227JEVK#TDFN support automatic pass-through mode verification?

Yes, the MAX17227JEVK#TDFN directly supports verification of automatic pass-through mode because it evaluates the MAX17227J IC, which inherently enables seamless conduction from input to output when VIN exceeds the programmed VOUT. This behavior is observable using the provided test points and jumpers - no firmware or external control is needed. The MAX17227JEVK#TDFN's schematic and layout preserve the IC's native pass-through functionality as specified in the MAX17227J datasheet.

How is output voltage configured on the MAX17227JEVK#TDFN?

Output voltage on the MAX17227JEVK#TDFN is selected using jumper JU2: shunt positions 1–2, 1–3, 1–4, and 1–5 configure 2.5V, 3.0V, 4.0V, and 5.0V respectively. The default setting is 5.0V (pins 1–5). For non-standard voltages, resistor R1 can be installed per the MAX17227J datasheet's RSEL table - the MAX17227JEVK#TDFN includes footprint and silkscreen for this option.

What input voltage is required to start up the MAX17227JEVK#TDFN?

The MAX17227JEVK#TDFN achieves typical startup at 0.88V with a 3kΩ load, consistent with the MAX17227J IC's ultra-low startup threshold. Operation is guaranteed from 400mV to 5.5V depending on load conditions. Users must ensure proper EN activation (via JU1 shunt on pins 1–2) and correct output voltage selection (JU2) before applying input power to avoid undervoltage lockout or misconfiguration.

Is the MAX17227JEVK#TDFN RoHS-compliant and lead-free?

Yes, the MAX17227JEVK#TDFN is RoHS-compliant, as indicated by the "#" suffix in the part number per Analog Devices' ordering nomenclature. All components on the board - including the pre-installed MAX17227JATA+, Murata capacitors, Würth inductor, and Vishay/Panasonic resistors - meet RoHS Directive 2011/65/EU requirements. Full compliance documentation is available in the official MAX17227J datasheet and Analog Devices' product change notices.
