Product details
Overview
MAX25203EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit for the MAX25203 dual-phase automotive synchronous boost controller. It enables engineers to validate cold-crank operation down to 1.8V input, generate backlight and Class D audio supply voltages (12V–65V), and evaluate I²C-monitored thermal protection and current sharing (±5% between phases) in automotive infotainment systems.
For engineers reviewing the MAX25203EVKIT# datasheet, MAX25203EVKIT# pinout, MAX25203EVKIT# application, or MAX25203EVKIT# equivalent, this board supports rapid validation of forced-PWM vs. skip-mode operation, spread-spectrum EMI reduction, external clock synchronization (FSYNC), and PWM-based output voltage control - all critical for AEC-Q100-compliant power design.
Technical Context
The MAX25203EVKIT# implements the MAX25203ATJA/VY+ controller in a side-wettable 32-pin TQFN-EP package, configured for 40V default output using external feedback (J1=1-2). It integrates two synchronous boost phases with cycle-by-cycle current limiting, die temperature monitoring via I²C, and PGOOD open-drain status reporting with onboard LED indication (J13).
Hardware features include jumper-selectable enable/shutdown (J10), PWM voltage control interface (J1=2-3, J26), FSYNC input for external clock synchronization (J28 open), and resistor-programmable switching frequency (200kHz–2.2MHz). The board uses six N-channel MOSFETs (NVMFS6H824NT1G) and one P-channel high-side switch (SMP3003-DL-1E) for gate drive and bias management.

FAQ
What is the primary function of the MAX25203EVKIT#?
The MAX25203EVKIT# is a fully assembled evaluation platform for the MAX25203 dual-phase synchronous boost controller. It allows engineers to validate cold-crank operation (down to 1.8V input), configure 12V–65V output voltages, test I²C-based diagnostics (die temperature, phase current), and evaluate EMI-reduction features including spread-spectrum and FSYNC synchronization - all under automotive-grade thermal and voltage stress conditions.
Does the MAX25203EVKIT# support PWM-based output voltage control?
Yes, the MAX25203EVKIT# supports PWM-based output voltage control. To enable it, set jumper J1 to position 2–3 (bypassing fixed feedback), remove the shunt from J26, and apply a PWM signal to the PWM terminal. This feature is documented in the MAX25203 data sheet and validated on the MAX25203EVKIT# hardware per its Quick Start guide and schematics.
Can the MAX25203EVKIT# operate in forced-PWM mode versus skip mode?
Yes, the MAX25203EVKIT# supports both modes via jumper J28. Set J28 to position 1–2 for forced-PWM (constant switching frequency across load range); set to 2–3 for skip mode (improved light-load efficiency). The board's default configuration (J28=1-2) enables forced-PWM, and both modes are electrically verified using the onboard MAX25203ATJA/VY+ controller.
What software tools are required to interface with the MAX25203EVKIT#?
The MAX25203EVKIT# requires the Windows-based SetupMAX25203EVkitV1.exe GUI installer, downloadable from maximintegrated.com/evkitsoftware. Once installed, the software communicates via USB (U2 module: MAX32625PICO) to monitor real-time parameters (die temperature, PGOOD status, phase currents) and adjust settings including output voltage, switching frequency, and protection thresholds - all leveraging the MAX25203's native I²C interface.
How is power enable/disable controlled on the MAX25203EVKIT#?
Enable/disable is controlled via jumper J10: position 1–2 enables the MAX25203 controller; position 2–3 disables it. For external logic control, remove the J10 shunt and apply a TTL/CMOS signal to pin 2 of J10. In shutdown mode, the MAX25203 reduces supply current to ≤5µA - a value confirmed by measurement and specified in the MAX25203 data sheet.
