Analog Devices Inc./Maxim Integrated MAX17632BEVKIT#

Overview

MAX17632BEVKIT# from Maxim Integrated is an evaluation kit for the MAX17632B - a 4.5V to 36V input, fixed 5V output, 2A synchronous step-down DC-DC converter in a 16-pin 3mm × 3mm TQFN package. It features peak-current-mode control, 400kHz–2.2MHz adjustable switching frequency, ±1.2% output voltage regulation over –40°C to +125°C, and supports PWM/DCM/PFM operation modes. The kit enables rapid validation of power delivery in industrial point-of-load and base station supply applications.

For engineers reviewing the MAX17632BEVKIT# datasheet, MAX17632BEVKIT# setup guide, MAX17632BEVKIT# test procedure, or MAX17632BEVKIT# alternative evaluation platforms, this kit provides verified reference design, BOM, layout, thermal performance data, and efficiency curves for the MAX17632B IC under real-world load, line, and temperature conditions - critical for pre-production power stage validation and compliance testing.

Technical Context

The MAX17632BEVKIT# implements the MAX17632B IC in a fully assembled, tested, and characterized configuration with a 5V/2A output. It uses a 10µH shielded inductor (XAL5050-103ME), 22µF/10V X7R output capacitor (GRM32ER71A226K), and all-ceramic input/output filtering - enabling compact, low-noise operation across its full 4.5V–36V input range. The board supports external clock synchronization via the MODE/SYNC pin and includes soft-start (SS) and RESET monitoring circuitry.

Designed per Maxim's EVKIT# standard, the kit integrates the IC's built-in compensation network and auxiliary EXTVCC bootstrap supply to maximize efficiency (up to 94% peak). It delivers validated performance in forced PWM, DCM, and PFM modes - with measured efficiency curves, load/line regulation (<±10mV), and hiccup-mode overload protection confirmed across –40°C to +125°C ambient.

FAQ

What is the purpose of the MAX17632BEVKIT#?

The MAX17632BEVKIT# is a fully assembled evaluation platform for the MAX17632B synchronous buck converter. It enables engineers to validate 5V/2A power delivery, measure efficiency, verify thermal behavior, test protection features (hiccup OCP, RESET, thermal shutdown), and assess EMI performance - all before committing to custom PCB design. The kit includes schematic, layout files, BOM, and test reports aligned with Maxim's official EVKIT documentation.

Does the MAX17632BEVKIT# support adjustable output voltage?

No - the MAX17632BEVKIT# is configured specifically for the MAX17632B variant, which has a fixed 5V output. It does not support output adjustment; the feedback resistor divider is omitted, and FB is directly connected to VOUT. For adjustable output evaluation, the MAX17632CEVKIT# (for MAX17632C) must be used instead.

Can the MAX17632BEVKIT# operate in PFM or DCM mode?

Yes - the MAX17632BEVKIT# supports all three operating modes via the MODE/SYNC pin. Leaving MODE/SYNC open enables PFM (pulse-frequency modulation) for light-load efficiency; connecting it to SGND forces constant-frequency PWM; tying it to VCC enables discontinuous conduction mode (DCM). Mode selection is verified in the kit's test reports with efficiency vs. load curves for each mode.

What input voltage range is validated on the MAX17632BEVKIT#?

The MAX17632BEVKIT# is validated across the full 4.5V to 36V input range per the MAX17632B datasheet. Test data confirms stable 5V regulation, <±10mV load/line regulation, and >90% efficiency at 2A load for VIN = 6.5V, 12V, 24V, and 36V - with thermal performance monitored up to +125°C ambient.

Is external clock synchronization supported on the MAX17632BEVKIT#?

Yes - the MAX17632BEVKIT# includes a dedicated MODE/SYNC connector that accepts external clock signals from 1.1× to 1.4× the internal f_SW. Synchronization capability is confirmed in oscilloscope waveforms (e.g., toc59/toc60) showing clean phase-locked operation at 440kHz and 560kHz with minimal jitter, supporting noise-sensitive multi-rail systems.
