Analog Devices Inc./Maxim Integrated MAX20812EVKIT#

Overview

MAX20812EVKIT# from Analog Devices is a fully assembled and tested evaluation kit for the MAX20812/MAX20812T dual-output step-down DC-DC switching regulator IC. It supports dual-output operation (1V/1.8V, up to 6A per rail) or single-output dual-phase mode (up to 12A), features a 2.7V–16V input range, 1000kHz/2000kHz programmable switching frequencies, and uses a 21-pin FC2QFN package IC. It is designed for power integrity validation in compact, high-efficiency point-of-load applications.

For engineers reviewing the MAX20812EVKIT# datasheet, MAX20812EVKIT# pinout, MAX20812EVKIT# application, or MAX20812EVKIT# equivalent, this kit enables rapid characterization of output voltage accuracy, load transient response, efficiency across 2.7V–16V input, dual-phase current sharing, and Bode plot stability margins - all with preconfigured test points, jumper-selectable modes, and proven PCB layout.

Technical Context

The MAX20812EVKIT# implements the MAX20812/MAX20812T IC in a reference design optimized for minimal component count and high power density. It integrates two independent synchronous buck regulators with integrated MOSFETs, 0.5V internal reference, and resistor-programmable PGMx pins for frequency, phase, and soft-start configuration.

It provides dual-rail monitoring via J2/J3 (VOUT1/VOUT2), LX waveform access at TP3/TP9, input sensing at TP5/TP6, and Bode analysis capability using 10Ω injection resistors at TP13–TP14 (VOUT1) and TP28–TP16 (VOUT2). The board supports both fixed-voltage operation and external bias via J32/J33 (3.3V).

FAQ

What is the primary function of the MAX20812EVKIT#?

The MAX20812EVKIT# is an evaluation platform for the MAX20812/MAX20812T dual-output buck regulator IC. It enables engineers to validate performance metrics including efficiency, load transient response, output voltage accuracy, and stability under real-world conditions - without designing custom hardware. The MAX20812EVKIT# ships fully assembled and tested with preconfigured 1V/1.8V outputs and comprehensive test point access.

Can the MAX20812EVKIT# be used to evaluate both MAX20812 and MAX20812T devices?

Yes, the MAX20812EVKIT# is explicitly designed to evaluate both the MAX20812 and MAX20812T ICs. These variants share identical pinout, electrical specifications, and functional behavior; the MAX20812T differs only in extended temperature grade (–40°C to +125°C vs. –40°C to +105°C for MAX20812). The MAX20812EVKIT# accommodates either device in its U1 socket and supports all operating modes for both parts.

How do I configure the MAX20812EVKIT# for dual-phase operation?

To configure the MAX20812EVKIT# for dual-phase operation, install 0Ω resistors at R2, R44, R45, and R48; remove R13; install a 0Ω resistor at R34; and use matched inductors L1/L2 (or a coupled two-phase inductor). Only EN1 and PGOOD1 remain active - EN2 and PGOOD2 are disconnected. This setup enables the MAX20812EVKIT# to deliver up to 12A on a single output while maintaining tight current sharing and thermal balance.

Does the MAX20812EVKIT# support efficiency measurement?

Yes, the MAX20812EVKIT# supports accurate efficiency measurement via dedicated VIN sense points TP5 (VIN_EFF_P) and TP6 (VIN_EFF_N), and standard VOUT monitoring at J2 (VOUT1) and J3 (VOUT2). These test points are isolated from regulation feedback paths to avoid loading errors, enabling precise calculation of η = (VOUT × IOUT) / (VIN × IIN) across full load and input voltage ranges.

What interfaces and monitoring features does the MAX20812EVKIT# provide?

The MAX20812EVKIT# provides J2/J3 for VOUT1/VOUT2 monitoring, TP3/TP9 for LX1/LX2 switching node waveforms, TP4/TP7 for VDDH/GND input monitoring, and TP13–TP14 and TP28–TP16 for Bode plot injection and measurement. It also includes SW1/SW2 toggle switches for output enable control, DS1/DS2 LEDs for PGOOD status indication, and J5/J8 banana jacks for input power connection.
