Analog Devices Inc./Maxim Integrated MAXM17624EVKIT#

Overview

MAXM17624EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the MAXM17624 synchronous step-down DC-DC power module operating at 3.3V output, 1A load, 4MHz switching frequency, and 95.2% peak efficiency (VIN=5V, VOUT=3.3V, IOUT=0.4A) in industrial power supply design.

For engineers reviewing the MAXM17624EVKIT# datasheet, MAXM17624EVKIT# pinout, MAXM17624EVKIT# application, or MAXM17624EVKIT# equivalent, this page provides verified board-level performance data, jumper-configurable PWM/PFM mode selection, PGOOD monitoring capability, and validated thermal and transient response under real load conditions.

Technical Context

The MAXM17624EVKIT# implements the MAXM17624 u-SLIC power module in a fixed 3.3V output configuration with internal 1ms soft-start, overcurrent/overtemperature protection, and selectable light-load PFM operation via jumper J2. It supports input voltage range 3.6V–5.5V and delivers up to 1A continuous output current.

Board-level features include pre-populated X7R ceramic input (C3 = 2.2µF/10V) and output (C4 = 10µF/16V) capacitors, optional damping tantalum capacitor (C2 = 47µF/8V) for hot-plug stability, and test loops on VIN, VOUT, PGND, EN, and PGOOD for direct probing without soldering.

FAQ

What is the primary function of the MAXM17624EVKIT#?

The MAXM17624EVKIT# is a ready-to-use evaluation platform for the MAXM17624 synchronous step-down power module. It provides immediate validation of 3.3V/1A output performance, including efficiency curves, load transients, startup behavior, and PGOOD signaling - all without assembly or layout effort. The MAXM17624EVKIT# includes pre-installed components, test points, and jumper-selectable modes to replicate real-world deployment conditions.

Does the MAXM17624EVKIT# support adjustable output voltage?

The MAXM17624EVKIT# is factory-configured for fixed 3.3V output using R1=118kΩ and R2=37.4kΩ. However, the underlying MAXM17624 module supports adjustable outputs from 1.5V to 3.3V via external feedback resistors. To modify output voltage, replace R1/R2 per Table 1 in the MAXM17624 datasheet - the MAXM17624EVKIT# PCB includes pads and routing compatible with such changes.

How do I configure PWM vs. PFM mode on the MAXM17624EVKIT#?

PWM or PFM mode is selected using jumper J2. Install J2 across pins 1–2 for constant-frequency PWM operation at all loads. Leave J2 uninstalled for default PFM operation at light loads (enhancing efficiency below ~100mA). Mode selection is latched at power-up and confirmed in the EV kit's Mode of Operation table (Rev 2, p.3).

What protection features are demonstrated by the MAXM17624EVKIT#?

The MAXM17624EVKIT# validates overcurrent protection (OCP) and overtemperature protection (OTP) as implemented in the MAXM17624 module. Performance reports include temporary output short testing (toc08) and thermal derating plots (toc12), confirming automatic shutdown and recovery under fault conditions. These protections are active without user configuration and require no external circuitry.

Can the MAXM17624EVKIT# be used with pre-biased outputs?

Yes - the MAXM17624EVKIT# demonstrates robust startup into pre-bias conditions, as shown in the "MAXM17624 STARTUP INTO PREBIAS" waveform (toc09). With VIN=5V and VPREBIAS=2.5V, the board achieves clean, monotonic 3.3V regulation without reverse current or output overshoot - validating suitability for hot-swap and redundant power rail applications.
