Analog Devices Inc./Maxim Integrated MAX17651EVKITA#

Overview

MAX17651EVKITA# from Analog Devices is an evaluation kit designed to demonstrate the performance of the MAX17651 high-voltage, ultra-low quiescent current linear regulator in a 6-pin TDFN package. It operates from 4V to 60V input, delivers up to 100mA output current, draws only 8µA no-load supply current, and supports jumper-configurable 3.3V/5V/12V outputs for industrial power-supply validation.

For engineers reviewing the MAX17651EVKITA# datasheet, MAX17651EVKITA# pinout, MAX17651EVKITA# application, or MAX17651EVKITA# equivalent, this EV kit enables rapid characterization of startup response, load transient behavior, PGOOD monitoring, thermal limits, and output voltage programming under real-world conditions with minimal external setup.

Technical Context

The MAX17651EVKITA# implements the MAX17651ATT+ (6-pin TDFN-EP) as the core regulator, featuring an internal pass transistor, precision feedback divider network (R4/R5), active-high enable control via JU1, and open-drain PGOOD output routed to a dedicated PCB pad. The board uses discrete ceramic and electrolytic capacitors optimized for stability across the full 4V–60V input range.

Output voltage selection is achieved through shunt jumpers (JU2/JU3/JU4) that configure the feedback node; resistor R4 is pre-installed for 5V default operation and can be replaced for custom outputs from 0.6V to 58V using R4 = 98.3 × (VOUT – 0.6) kΩ. Thermal performance is characterized with θJA = 42°C/W under no-airflow conditions.

FAQ

What is the primary function of the MAX17651EVKITA# evaluation kit?

The MAX17651EVKITA# evaluation kit is a fully assembled and tested circuit board that demonstrates the electrical and thermal performance of the MAX17651ATT+ high-voltage, ultra-low quiescent current linear regulator. It enables engineers to validate startup behavior, load transients, PGOOD response, and output voltage accuracy across its 4V–60V input range without designing a custom PCB.

Which regulator IC is installed on the MAX17651EVKITA# board?

The MAX17651EVKITA# board is populated with the MAX17651ATT+, a 6-pin TDFN-EP packaged linear regulator rated for 4V–60V input and up to 100mA output. This device is the exact component evaluated by the kit and is factory-installed with verified layout and component selection per Analog Devices' reference design.

How do I configure the MAX17651EVKITA# for 3.3V output?

To configure the MAX17651EVKITA# for 3.3V output, install a shunt on jumper JU3 (leaving JU2 and JU4 open). The minimum required input voltage for stable 3.3V regulation is 4.4V. Confirm operation using a DMM across the VOUT and GND pads after enabling the input supply and verifying EN is asserted via JU1 position 1–2.

Does the MAX17651EVKITA# support custom output voltages beyond 3.3V, 5V, or 12V?

Yes - the MAX17651EVKITA# supports custom output voltages from 0.6V to 58V by replacing resistor R4. The required value is calculated as R4 = 98.3 × (VOUT – 0.6) kΩ. For outputs above 12V, ensure the output capacitor C3 is replaced with one rated ≥1.2× the programmed VOUT, as the default 16V-rated C3 is insufficient above 12V.

What thermal limitations apply to the MAX17651EVKITA# during operation?

The MAX17651EVKITA# has a measured θJA of 42°C/W under no-airflow conditions. To maintain MAX17651ATT+ junction temperature ≤125°C, maximum allowable load current must be calculated per ILOAD(MAX) = (125 – TA_MAX) / [0.042 × (VIN – VOUT)]. For example, at TA_MAX = +70°C, VIN = 24V, and VOUT = 5V, the safe continuous load is ~69mA.
