Analog Devices Inc./Maxim Integrated MAX25202EVKIT#

Overview

The MAX25202EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to simplify validation of the MAX25202 400kHz, 36V synchronous boost controller IC. It features automotive-grade components, jumper-configurable operation modes (FPWM/skip), ±2% output voltage accuracy, and supports adjustable boost outputs from 4.5V to 60V - used for evaluating high-reliability DC-DC conversion in automotive infotainment power rails.

For engineers reviewing the MAX25202EVKIT# datasheet, MAX25202EVKIT# pinout, MAX25202EVKIT# application, or MAX25202EVKIT# equivalent, this board enables rapid functional verification of MAX25202 variants including frequency synchronization, PGOOD monitoring, and input voltage extension down to 2V post-startup - critical for 12V/24V vehicle systems with cold-crank transients.

Technical Context

The MAX25202EVKIT# implements two independent MAX25202 controller channels - U1 (MAX25202MATEA/VY+) and U2 (MAX25202SATEA/VY+) - both in 16-pin WETQFN packages. Each channel supports forced-PWM or skip-mode operation via FSYNCIN logic level, and provides dedicated test points for SUP, OUT, PGOOD, FSYNCIN, and COMP nodes.

It integrates dual 2.2µH power inductors (XAL1060-222ME), 120µF bulk output capacitors (EEH-ZC1H121P), and automotive-rated MOSFETs (DMTH6009LPS) to sustain 200W load capability. The board's proven PCB layout includes internal layer 2/3 power planes and thermal relief optimized for 42V transient immunity and EMI control.

FAQ

What is the primary function of the MAX25202EVKIT#?

The MAX25202EVKIT# is an evaluation platform for the MAX25202 synchronous boost controller IC. It enables hardware validation of key features including 400kHz switching, 4.5V–36V input range, 24V default output, PGOOD monitoring, and FSYNC synchronization. The MAX25202EVKIT# includes dual controller channels, automotive-grade passives, and test points for real-time signal analysis - accelerating development of automotive power supplies.

Which MAX25202 variants does the MAX25202EVKIT# support out-of-the-box?

The MAX25202EVKIT# ships with two installed ICs: U1 = MAX25202MATEA/VY+ and U2 = MAX25202SATEA/VY+, both in 16-pin WETQFN packages. Per the EV Kit Bill of Materials and schematic, it natively supports evaluation of synchronous boost variants. Minor component changes - documented in the MAX25202 EV Kit BOM - allow adaptation to spread-spectrum or other MAX25202 family members.

How do I configure the MAX25202EVKIT# for skip mode versus forced-PWM mode?

Skip mode versus forced-PWM is controlled by jumper J2 on the MAX25202EVKIT#. With J2 shunted at positions 1–2, FSYNCIN is pulled to VBIAS, enabling forced-PWM across all loads. To enable skip mode (for improved light-load efficiency), remove the J2 shunt to float FSYNCIN - the MAX25202EVKIT# then automatically transitions between skip and PWM based on load current, as defined in the MAX25202 IC datasheet.

Can the MAX25202EVKIT# be used to evaluate output voltages other than 24V?

Yes - the MAX25202EVKIT# supports adjustable output voltages from 4.5V to 60V. Its default 24V regulation is set by resistors R9 (115kΩ) and R10 (4.99kΩ). To change output voltage, replace R9 and/or R10 per the formula V_OUT = V_FB × (1 + R9/R10), where V_FB = 1.215V. All required resistor footprints are present on the MAX25202EVKIT# PCB.

Does the MAX25202EVKIT# include provisions for external clock synchronization?

Yes - the MAX25202EVKIT# provides a dedicated FSYNCIN test point and compatible circuitry to accept external clock signals from 220kHz to 2.2MHz. When an external clock is applied to FSYNCIN, the MAX25202EVKIT# forces PWM operation and locks the switching frequency to the input clock. This capability is verified in the MAX25202EVKIT# schematic and Quick Start procedure using the FSYNCIN node.
