Analog Devices Inc./Maxim Integrated MAXM17532EVKIT#

Overview

MAXM17532EVKIT# from Maxim Integrated is an evaluation kit for the MAXM17532 Himalaya uSLIC™ step-down power module - a fully integrated, synchronous DC-DC converter delivering up to 100mA at 0.9V–5.5V output from a 4V–42V input. It features peak-current-mode control, programmable soft-start (5.1ms default), open-drain RESET output, and operates across –40°C to +125°C ambient. Designed for rapid prototyping of compact industrial power rails.

For engineers reviewing the MAXM17532EVKIT# datasheet, MAXM17532EVKIT# pinout, MAXM17532EVKIT# application, or MAXM17532EVKIT# equivalent, this kit enables immediate validation of MAXM17532 performance in 4–42V input systems requiring <100mA regulated output, pre-biased startup, PFM/PWM mode selection, and CISPR22 Class B compliance - without custom PCB design.

Technical Context

The MAXM17532EVKIT# implements the MAXM17532 power module in a fixed 5V/100mA configuration with all critical external components pre-installed: 2.2µF CIN (C2012X7R1H225K125AC), 10µF COUT (GRM21BR70J106K), 69.8kΩ RT/SYNC resistor, and feedback divider (R1=261kΩ, R2=49.9kΩ). It supports both PWM (MODE=GND) and PFM (MODE=open) operation, with verified soft-start, hiccup overcurrent protection, and thermal shutdown at +160°C.

Board-level features include EN/UVLO programming via onboard resistor network, SS pin accessible for adjustable soft-start capacitor addition, RESET pull-up resistor, and layout-optimized 4-layer PCB matching Maxim's land pattern 90-100027. Input voltage range is validated from 4V to 42V, with measured efficiency >85% at 24V_IN/5V_OUT/100mA in PWM mode.

FAQ

What is the primary function of the MAXM17532EVKIT#?

The MAXM17532EVKIT# is an evaluation kit designed exclusively to demonstrate and validate the MAXM17532 Himalaya uSLIC™ step-down power module. It provides a fully assembled, tested PCB with all required passive components (input/output capacitors, feedback resistors, RT/SYNC resistor), enabling immediate bench testing of 4V–42V input conversion to regulated 5V/100mA output - including soft-start, RESET signaling, PFM/PWM mode switching, and thermal protection behavior.

Does the MAXM17532EVKIT# support adjustable output voltage?

Yes - while the MAXM17532EVKIT# ships configured for 5V output using R1=261kΩ and R2=49.9kΩ, the feedback divider is accessible via test points and solder jumpers. Engineers can replace R1/R2 to program any output between 0.9V and 5.5V per the MAXM17532 datasheet equation V_OUT = 0.812V × (1 + R1/R2), maintaining stability by selecting the appropriate RT/SYNC resistor per Table 1 for the chosen V_OUT and f_SW.

Can the MAXM17532EVKIT# be used to evaluate pre-biased startup?

Yes - the MAXM17532EVKIT# fully supports monotonic startup into a pre-biased output, as implemented in the underlying MAXM17532 device. When powered with V_OUT already present (e.g., from another rail), the kit's MAXM17532 enters a high-impedance state until its internal reference ramps, preventing reverse current flow. This behavior is confirmed in typical operating characteristics Figure toc12 and documented in the "Startup Into a Pre-biased Output" section of the MAXM17532 datasheet.

What are the key EMI and compliance features validated on the MAXM17532EVKIT#?

The MAXM17532EVKIT# implements the MAXM17532's built-in EMI mitigation: integrated inductor shielding, optimized internal FET timing, and layout-verified filtering. It meets CISPR22 (EN55022) Class B conducted and radiated emissions requirements per the MAXM17532 datasheet, and passes JESD22-B103 (drop), B104 (shock), and B111 (vibration) mechanical reliability standards - all validated on the evaluation board's 4-layer construction matching land pattern 90-100027.

Is external synchronization supported on the MAXM17532EVKIT#?

Yes - the MAXM17532EVKIT# exposes the RT/SYNC pin with a 47pF AC-coupling capacitor footprint and series resistor pad, enabling direct connection to an external clock source as shown in Figure 1 of the MAXM17532 datasheet. The onboard 69.8kΩ RT resistor must be removed or lifted to enable synchronization; the external clock must operate 10% above the desired f_SW, with logic-high >3V, logic-low <0.5V, and 10–70% duty cycle.
