Analog Devices Inc./Maxim Integrated MAXM17633EVKIT#

Overview

MAXM17633EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to assess the performance of the MAXM17633, MAXM17634, and MAXM17635 uSLIC™ step-down power modules. It supports three independent module configurations: 3.3V/2A (800kHz), 5V/2A (1MHz), and adjustable 12V/2A (1.8MHz), each with programmable UVLO, soft-start, mode selection (PWM/PFM/DCM), and external clock synchronization - enabling rapid validation in industrial power supply design.

For engineers reviewing the MAXM17633EVKIT# datasheet, MAXM17633EVKIT# pinout, MAXM17633EVKIT# application, or MAXM17633EVKIT# equivalent, this kit provides pre-validated PCB layouts, CISPR22 Class B EMI-compliant operation, real-time load-transient response measurement points, and jumper-configurable operating modes - critical for evaluating high-efficiency, wide-input DC-DC conversion in space-constrained embedded systems.

Technical Context

The MAXM17633EVKIT# hosts three electrically isolated evaluation circuits on a single PCB, each configured for its respective module's optimal input range (4.5–36V, 7–36V, or 18–36V) and output specification. Each circuit includes resistor-programmable EN/UVLO thresholds, selectable MODE/SYNC jumpers for PWM/PFM/DCM operation, and dedicated soft-start capacitors set to 1ms default timing.

It integrates EMI mitigation features including input X7R ceramic capacitors (C102/C202/C302 = 4.7µF/50V), optional electrolytic damping caps (C101/C201/C301 = 10µF/50V), and optimized layout techniques that meet CISPR22 Class B conducted and radiated emissions limits across all three modules under full-load PWM operation.

FAQ

What does MAXM17633EVKIT# evaluate?

MAXM17633EVKIT# evaluates the MAXM17633, MAXM17634, and MAXM17635 uSLIC™ step-down power modules. It provides three independent, fully assembled circuits - one for each module - supporting fixed 3.3V/5V and adjustable 12V outputs at up to 2A. The kit enables comprehensive testing of efficiency, transient response, EMI, startup behavior, and mode switching without requiring custom PCB design.

Does MAXM17633EVKIT# support external clock synchronization?

Yes, MAXM17633EVKIT# supports external clock synchronization for all three modules via the MODE/SYNC pin. When configured in PWM or DCM mode using jumpers JU102/JU202/JU302, the internal oscillator can be synchronized to an external clock signal between 1.1× and 1.4× the programmed switching frequency - allowing precise timing alignment in multi-rail or noise-sensitive systems.

How is undervoltage lockout (UVLO) configured on MAXM17633EVKIT#?

UVLO on MAXM17633EVKIT# is resistor-programmable via voltage dividers (RU/RB) and controlled by jumpers JU101/JU201/JU301. With jumpers open, UVLO triggers at 4.05V (MAXM17633), 6.3V (MAXM17634), or 16.2V (MAXM17635). Installing shunts across pins 2–3 disables the module; installing across 1–2 connects EN directly to VIN for low-threshold enable. Values are calculated using RU = 3.32MΩ and RB derived from V_{IN_U} = 1.215V × (1 + RU/RB).

Can MAXM17633EVKIT# be used to evaluate load-transient response?

Yes, MAXM17633EVKIT# includes dedicated test points and documented waveforms for load-transient response across all three modules and operating modes. Performance plots (e.g., toc28–toc37) show VOUT recovery under 0→1A, 1→2A, and 20mA→1A steps in PWM, PFM, and DCM modes - enabling direct assessment of control-loop stability and output capacitor effectiveness in real-world dynamic conditions.

Is MAXM17633EVKIT# RoHS compliant and EMI certified?

Yes, MAXM17633EVKIT# is RoHS compliant (denoted by # symbol in ordering info) and meets CISPR22 Class B limits for both conducted and radiated emissions. EMI compliance is achieved through integrated input filtering (X7R ceramics + optional electrolytics), optimized PCB stack-up (4-layer), and layout techniques verified across all three modules - with test data presented in plots toc51–toc56 of the official documentation.
