Analog Devices Inc./Maxim Integrated MAXM15464EVKIT#

Overview

MAXM15464EVKIT# from Maxim Integrated is an evaluation kit designed to validate the MAXM15464 high-voltage synchronous step-down DC-DC module delivering a fixed 5V output at up to 300mA, operating from 12V–42V input, with 84.7% efficiency at 24V_IN/5V_OUT/150mA, and featuring PFM/PWM mode selection, adjustable UVLO, and open-drain RESET for industrial power supply design verification.

For engineers reviewing the MAXM15464EVKIT# datasheet, MAXM15464EVKIT# pinout, MAXM15464EVKIT# application, or MAXM15464EVKIT# equivalent, this page provides verified board-level performance data, jumper configuration guidance (J1/J2), EMI-compliant layout validation, load transient response waveforms, and direct correlation to the MAXM15464 module's electrical behavior under real-world test conditions.

Technical Context

The MAXM15464EVKIT# implements the MAXM15464 micro-SLIC power module in a fully assembled, tested PCB layout optimized for CISPR22 Class B conducted and radiated emissions compliance. It supports dual operation modes-PFM for light-load efficiency and PWM for stable frequency control-selected via jumper J2, while enabling precise input voltage startup control through resistor-programmable EN/UVLO using R1 (2.2MΩ) and R2 (249kΩ).

Board-level features include integrated EMI filtering (C7/C8/C9 + L1), hot-plug damping (C2), internal LDO bypassing (C4), and output regulation monitoring via RESET signal. Performance validation includes efficiency vs. load curves (1–300mA), output voltage line/load regulation (±2.5mV over 12–36V_IN, ±5mV over 0–300mA), and Bode plot stability analysis (61.155° phase margin at 50.57kHz crossover).

FAQ

What is the primary function of the MAXM15464EVKIT#?

The MAXM15464EVKIT# is a fully assembled evaluation kit that demonstrates and validates the performance of the MAXM15464 5V fixed-output synchronous step-down DC-DC module. It enables engineers to verify key parameters-including efficiency, load/transient response, EMI behavior, and startup sequencing-under real operating conditions before integrating the MAXM15464 into end equipment.

How do I configure the MAXM15464EVKIT# for PFM versus PWM operation?

Configure the MAXM15464EVKIT# for PFM mode by leaving jumper J2 uninstalled; this enables automatic light-load efficiency optimization. For constant-frequency PWM operation across all loads, install jumper J2 across pins 1–2. Both configurations are validated per the MAXM15464EVKIT# datasheet and reflected in its published efficiency vs. load curves.

Does the MAXM15464EVKIT# support adjustable input undervoltage lockout (UVLO)?

Yes-the MAXM15464EVKIT# supports resistor-programmable UVLO via R1 (2.2MΩ) and R2 (249kΩ). With J1 open, the MAXM15464 activates when input voltage exceeds 12V. Installing a jumper across J1 pins 2–3 disables the module. The UVLO threshold is calculated using the MAXM15464's internal 1.215V reference and confirmed in Table 1 of the MAXM15464EVKIT# documentation.

What EMI mitigation components are included on the MAXM15464EVKIT#?

The MAXM15464EVKIT# includes a full CISPR22 Class B-compliant EMI filter: C7 (0.1µF), C8 (0.68µF), C9 (1µF), and L1 (82µH), arranged as shown in Figure 1. This filter reduces both conducted and radiated emissions, with test data confirming compliance under 24V_IN/5V_OUT/300mA conditions-enabling faster regulatory approval for derivative designs.

Can the MAXM15464EVKIT# be used to evaluate load transient response?

Yes-the MAXM15464EVKIT# provides documented load transient waveforms (toc08 and toc09), showing output voltage deviation during 150mA→300mA (PWM) and 5mA→150mA (PFM) steps at 24V_IN. These measurements confirm stable regulation with <±20mV excursion and fast recovery, validating dynamic performance for applications like FPGA core supplies or sensor interface rails.
