Analog Devices Inc./Maxim Integrated MAX17626EVKIT#

Overview

MAX17626EVKIT# from Analog Devices is an evaluation kit designed to validate the performance of the MAX17626 synchronous step-down DC-DC converter, configured for 3.3V output at up to 700mA load current over a 3.6V–5.5V input range, operating at a fixed 4MHz switching frequency with selectable PWM/PFM mode and integrated PGOOD signaling.

For engineers reviewing the MAX17626EVKIT# datasheet, MAX17626EVKIT# pinout, MAX17626EVKIT# application, or MAX17626EVKIT# equivalent, this kit supports rapid validation of high-frequency power delivery in space-constrained industrial and portable systems requiring stable 3.3V rail generation, soft-start timing, and efficiency benchmarking at 94.5% (VIN = 5V, VOUT = 3.3V, IOUT = 500mA).

Technical Context

The MAX17626EVKIT# hosts a fully assembled, tested MAX17626ATA+ TDFN8-EP IC with optimized PCB layout, including 2.2μF/10V input capacitor (C203), 10μF/10V X7R output capacitor (C206), and 1μH/3.8A shielded inductor (L201). It implements resistor-divider-based output voltage setting (R201/R202) and provides jumper-selectable EN and MODE control via JU201 and JU202.

It supports two operational modes: PWM (shunt installed on JU202 pins 1–2) for consistent frequency under all loads, and PFM (shunt removed) for improved light-load efficiency. The board includes hot-plug mitigation with 47μF/8V tantalum capacitor (C202) and local high-frequency decoupling (C201/C204/C207).

FAQ

What does the MAX17626EVKIT# evaluate?

The MAX17626EVKIT# evaluates the MAX17626 synchronous step-down DC-DC converter, specifically its 3.3V output configuration delivering up to 700mA from a 3.6V–5.5V input at 4MHz switching frequency. It includes full circuit implementation with input/output filtering, mode selection jumpers, and PGOOD monitoring - enabling direct functional and efficiency validation of the MAX17626 device without additional design effort.

Can the MAX17626EVKIT# be used to test different output voltages?

Yes - the MAX17626EVKIT# supports adjustable output voltage from 1.5V to 3.3V using the onboard resistor divider (R201/R202). While factory-configured for 3.3V, users can replace R201 (118kΩ) and/or R202 (37.4kΩ) to set alternate voltages per the MAX17626 data sheet's feedback network equation. No PCB modification beyond resistor replacement is required.

How do I configure PWM vs. PFM mode on the MAX17626EVKIT#?

On the MAX17626EVKIT#, PWM mode is enabled by installing a shunt on jumper JU202 pins 1–2 (connecting MODE to GND); PFM mode is selected by leaving JU202 unshunted (open), allowing automatic light-load mode transition. This matches the MAX17626's native control logic and is documented in Table 2 of the EV kit user guide.

Does the MAX17626EVKIT# include input protection for hot-plug scenarios?

Yes - the MAX17626EVKIT# includes a 47μF/8V tantalum capacitor (C202) placed near the input to dampen voltage oscillations caused by long cables or hot-plug events. Its ESR helps suppress ringing induced by cable inductance, protecting the MAX17626 input stage during dynamic power application - a feature explicitly implemented per the MAX17626 data sheet recommendations.

Is the MAX17626EVKIT# fully assembled and tested before shipment?

Yes - the MAX17626EVKIT# ships fully assembled and factory-tested, including the MAX17626ATA+ IC in TDFN8-EP package, all passive components (inductor L201, capacitors C201–C207, resistors R201–R203), and silkscreen-labeled test points. No soldering or component placement is needed prior to initial power-up and functional verification.
