Analog Devices Inc./Maxim Integrated MAXM17712EVKIT#

Overview

MAXM17712EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to validate the performance of the MAXM17712, MAXM17720, and MAXM17724 micro-SLIC power modules. It supports wide-input operation (5.5V–60V), delivers up to 150mA from the step-down converter and 50mA from the linear regulator per module, and includes configurable EN/UVLO, PWM/PFM mode selection, and external clock synchronization - enabling rapid prototyping of industrial and embedded power subsystems.

For engineers reviewing the MAXM17712EVKIT# datasheet, MAXM17712EVKIT# pinout, MAXM17712EVKIT# application, or MAXM17712EVKIT# equivalent, this kit provides verified PCB layout, CISPR22 Class B EMI compliance data, load transient waveforms, Bode plots, and startup/shutdown timing for all three module variants on a single board - accelerating design validation and regulatory pre-compliance testing.

Technical Context

The MAXM17712EVKIT# hosts three electrically isolated evaluation circuits on one PCB: one for MAXM17712 (3.3V buck + 1.8V LDO), one for MAXM17720 (5V buck + 3.3V LDO), and one for MAXM17724 (adjustable 2.5V–5V buck + 2.5V LDO). Each circuit includes resistor-programmable UVLO thresholds, jumper-selectable PWM/PFM modes, and RT-resistor-configurable switching frequencies (375kHz for MAXM17712; 570kHz for MAXM17720/MAXM17724).

It integrates EMI filter components (82µH inductor, 0.47µF/1µF capacitors) and optional input damping capacitors (4.7µF/100V) to suppress hot-plug oscillations and meet CISPR22 Class B conducted/radiated emissions limits. All modules feature RESET outputs pulled to their respective output voltages and support external clock synchronization with ≥100ns pulse-width tolerance.

FAQ

What modules does the MAXM17712EVKIT# evaluate?

The MAXM17712EVKIT# evaluates three distinct power modules on a single PCB: MAXM17712 (3.3V fixed-output buck + 1.8V LDO), MAXM17720 (5V fixed-output buck + 3.3V LDO), and MAXM17724 (adjustable 2.5V–5V buck + 2.5V LDO). Each module has independent input, output, enable, and configuration jumpers - allowing concurrent or isolated evaluation without hardware modification. The MAXM17712EVKIT# schematic and layout are publicly documented in Maxim's EV kit data sheet.

Does the MAXM17712EVKIT# support external clock synchronization?

Yes, the MAXM17712EVKIT# supports external clock synchronization for all three modules via dedicated MODE/SYNC pins (MODE/SYNC1, MODE/SYNC2, MODE/SYNC3). Each pin accepts an external clock signal between 1.1×fSW and 1.4×fSW (e.g., 413–525kHz for MAXM17712; 627–798kHz for MAXM17720/MAXM17724), with minimum on/off time ≥100ns. Jumpers JU12/JU22/JU32 must be open to enable synchronization mode on the MAXM17712EVKIT#.

How is undervoltage lockout (UVLO) configured on the MAXM17712EVKIT#?

UVLO is resistor-programmable per module using voltage-divider networks: R11/R12 (3.32MΩ/953kΩ) sets MAXM17712 startup at 5.5V; R21/R22 and R31/R32 (3.32MΩ/562kΩ each) set MAXM17720 and MAXM17724 startup at 8.4V. Jumpers JU11/JU21/JU31 default to open for normal operation; installing shunts across pins 1–2 disables the respective module. Configuration details are provided in Table 1 of the MAXM17712EVKIT# data sheet.

What EMI filtering components are included on the MAXM17712EVKIT#?

The MAXM17712EVKIT# includes optional EMI filter components: LEMI_1 (82µH shielded inductor), CEMI_1 (0.47µF/100V X7R ceramic), and CEMI_2 (1µF/100V X7R ceramic). When installed, this filter reduces conducted emissions below CISPR22 Class B limits. The PCB layout also minimizes radiated emissions via optimized switching node routing and local 0.1µF high-frequency decoupling (C14/C24/C34) near each module's input.

Can the MAXM17712EVKIT# be used to evaluate load transient response?

Yes, the MAXM17712EVKIT# provides direct access to VOUTB, VOUTL, LX, and IOUT test points for precise load transient measurement. Published performance reports include scope captures for 5mA→75mA and 75mA→150mA buck load steps (toc11–toc14), plus LDO load transients (1mA→25mA and 25mA→50mA, toc31–toc36), all under both PWM and PFM modes - enabling direct comparison of dynamic regulation performance across all three modules.
