Analog Devices Inc./Maxim Integrated MAXM17632EVKIT#

Overview

MAXM17632EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to assess the MAXM17632 adjustable 12V, 1A uSLIC™ step-down power module operating from 20V–36V input at 2.15MHz switching frequency. It supports PWM/DCM/PFM mode selection, external clock synchronization, resistor-programmable UVLO (19.5V startup), and delivers 93.12% efficiency at 24V_IN/12V_OUT/1A. The kit enables rapid validation of high-density DC-DC conversion in industrial power rails.

For engineers reviewing the MAXM17632EVKIT# datasheet, MAXM17632EVKIT# pinout, MAXM17632EVKIT# application, or MAXM17632EVKIT# equivalent, this board provides verified PCB layout, CISPR22 Class B EMI compliance, load transient response characterization (0–0.5A/0.5–1A steps), Bode plot stability data (89.8kHz crossover, 70.7° phase margin), and configurable EN/UVLO, MODE/SYNC, and output voltage settings.

Technical Context

The MAXM17632EVKIT# hosts the MAXM17632AME+ module - a 16-pin uSLIC™ integrated power solution combining controller, MOSFETs, and inductor. It implements constant-on-time (COT) control with internal compensation, enabling fast transient response without external loop components. The kit's three independent channels (MAXM17630/MAXM17631/MAXM17632) are electrically isolated on one PCB for comparative testing.

Input EMI filtering uses 4.7µF X7R ceramic + 10µF aluminum electrolytic capacitors; output employs 10µF/50V X7R ceramic (C307). Switching frequency is set by R303 (8.2kΩ) to 2150kHz. UVLO threshold is configured via R301 (3.3MΩ) and R302 (215kΩ); MODE/SYNC operation is selected via jumper JU302 positions (open = PFM, 1–2 = DCM, 2–3 = PWM).

FAQ

What does MAXM17632EVKIT# evaluate specifically?

MAXM17632EVKIT# evaluates the MAXM17632AME+ 16-pin uSLIC™ step-down power module configured for 12V/1A output. It provides full access to EN/UVLO, MODE/SYNC, and feedback pins, enabling verification of startup behavior, efficiency across load range (10mA–1A), transient response, EMI performance, and stability margins per the MAXM17632 data sheet.

Can MAXM17632EVKIT# be used to evaluate other modules in the family?

Yes - MAXM17632EVKIT# is part of a shared three-channel evaluation platform that also hosts MAXM17630AME+ (3.3V/1A) and MAXM17631AME+ (5V/1A) modules. Each channel operates independently with dedicated input/output pads, jumpers (JU101–JU302), and resistor networks, allowing side-by-side comparison of different output voltages and switching frequencies.

How is output voltage adjusted on MAXM17632EVKIT#?

MAXM17632EVKIT#'s output is preset to 12V using R305=634kΩ and R306=51kΩ in the feedback divider. To adjust V_OUT, replace these resistors per the formula V_OUT = 0.9V × (1 + R305/R306). The MAXM17632 data sheet Table 2 provides standard values for common outputs from 0.9V to 12V.

What input voltage range must be applied to MAXM17632EVKIT#?

MAXM17632EVKIT# requires 20V to 36V DC input applied to VIN_EMI3 and PGND3 pads. This matches the MAXM17632AME+ module's specified input range. Applying voltage below 20V will prevent startup due to the factory-configured 19.5V UVLO threshold; exceeding 36V risks damage to onboard components.

Does MAXM17632EVKIT# support external clock synchronization?

Yes - the MODE/SYNC pin (pin 4 of U301) accepts an external clock signal between 1.1× and 1.4× the programmed switching frequency (i.e., 2.37–3.01MHz for MAXM17632EVKIT#'s 2150kHz setting). Jumper JU302 must be left open, and the external clock must meet minimum pulse width requirements (high >50ns, low >160ns).
