Analog Devices Inc./Maxim Integrated MAX17536EVKITA#

Overview

MAX17536EVKITA# from Maxim Integrated is an evaluation kit for the MAX17536 4.5V–60V, 4A synchronous step-down DC-DC converter with integrated high-side MOSFET, internal compensation, and adjustable switching frequency (100kHz–2.2MHz). It supports 5V/4A and 3.3V/4A reference designs, features built-in soft-start, open-drain RESET, and operates across –40°C to +125°C ambient.

For engineers reviewing the MAX17536EVKITA# datasheet, MAX17536EVKITA# pinout, MAX17536EVKITA# application, or MAX17536EVKITA# equivalent, this kit enables rapid validation of high-voltage industrial POL regulation, wall transformer replacement, and base-station power architectures under real-world load, thermal, and transient conditions.

Technical Context

The MAX17536EVKITA# implements the full functional interface of the MAX17536 IC-including EN/UVLO threshold programming, MODE/SYNC mode selection (PWM/PFM/DCM), RT-based frequency tuning, FB voltage regulation (0.9V ±1.4%), and EXTVCC auxiliary LDO switchover-on a validated multilayer PCB with optimized thermal vias and layout per Maxim's land pattern 90-0009.

It integrates all critical passive components for 5V/4A operation: XAL6060-472ME inductor, SIS468DN low-side MOSFET, Murata GRM32ER71A476KE15 (47µF) and GRM32ER71A226K (22µF ×2) output capacitors, and TDK C1005X7R1H104K050BB (0.1µF) BST capacitor, enabling immediate bench testing without component sourcing.

FAQ

What is the primary function of the MAX17536EVKITA# evaluation kit?

The MAX17536EVKITA# is a fully assembled and tested evaluation platform for the MAX17536 synchronous step-down DC-DC converter. It allows engineers to validate performance-including efficiency, transient response, thermal behavior, and protection features-under real operating conditions using standard lab equipment, without custom PCB design or component selection.

Does the MAX17536EVKITA# support both 5V and 3.3V output configurations?

Yes, the MAX17536EVKITA# supports both 5V/4A and 3.3V/4A output configurations as documented in Figures 3 and 4 of the MAX17536 datasheet. Output voltage is set via FB resistor divider; the kit includes populated components for 5V operation and provides footprint options for 3.3V reconfiguration.

Can the MAX17536EVKITA# be synchronized to an external clock signal?

Yes, the MAX17536EVKITA# supports external synchronization via the MODE/SYNC pin. When an external clock between 1.1× and 1.4× the programmed f_SW is applied, the MAX17536 inside the kit locks to that frequency-enabling noise-sensitive system-level timing alignment and EMI reduction.

What thermal management features are implemented on the MAX17536EVKITA# PCB?

The MAX17536EVKITA# PCB implements Maxim's recommended thermal design: the exposed pad (EP) is soldered directly to a large SGND copper plane and connected via ≥6 thermal vias to inner ground layers. This achieves θ_JA = 23°C/W on a 4-layer board, supporting continuous 4A operation at +70°C ambient.

How does the MAX17536EVKITA# handle undervoltage lockout and soft-start?

The MAX17536EVKITA# implements programmable EN/UVLO via a resistor divider on the EN/UVLO pin (threshold: 1.215V rising) and adjustable soft-start via a capacitor on the SS pin (typical 4.7µA charging current). These functions are fully accessible and testable on the board, enabling precise control of turn-on sequencing and inrush current limiting.
