Analog Devices Inc./Maxim Integrated MAX20828TEVKIT#

Overview

MAX20828TEVKIT# from Analog Devices is a fully assembled and tested evaluation kit designed to validate the MAX20828T dual-output step-down DC-DC switching regulator IC in real-world power delivery applications. It supports up to 8A per output (16A in dual-phase mode), operates from 2.7V–16V input, delivers 0.5V–5.8V programmable outputs, and features FC2QFN-21 packaging for high power density.

For engineers reviewing the MAX20828TEVKIT# datasheet, MAX20828TEVKIT# pinout, MAX20828TEVKIT# application, or MAX20828TEVKIT# equivalent, this kit enables rapid validation of dual-rail sequencing, efficiency at 1MHz/2MHz switching frequencies, soft-start behavior, PGOOD monitoring, and bode plot characterization - all with pre-validated PCB layout and test point access.

Technical Context

The MAX20828TEVKIT# implements the MAX20828T IC in dual-output configuration by default (1V on rail 1, 1.8V on rail 2), with jumper-selectable dual-phase operation that merges both channels into a single 16A output using shared control loop EN1/PGOOD1. The board integrates full input/output connectivity via banana jacks (J5/J8), edge connectors (J12/J13), and precision test points (TP5/TP6 for VIN, J2/J3 for VOUT).

It provides hardware-level configurability through PGMx resistors (R11/R21/R35) for switching frequency (1MHz/2MHz), AMS/DCM mode selection, and output mode (dual vs. dual-phase), while supporting soft-start ramp time of 3ms, pre-biased startup, and real-time status monitoring via DS1/DS2 LEDs and PGOOD signals routed to J10/J11.

FAQ

What is the primary function of the MAX20828TEVKIT#?

The MAX20828TEVKIT# is a fully assembled evaluation kit for the MAX20828T dual-output step-down DC-DC regulator IC. It enables engineers to validate performance parameters including efficiency, transient response, thermal behavior, and sequencing - without requiring custom PCB design. The MAX20828TEVKIT# includes all necessary jumpers, test points, and connectors to characterize the MAX20828T across its full operating range.

Can the MAX20828TEVKIT# be used for dual-phase operation?

Yes, the MAX20828TEVKIT# supports dual-phase configuration by installing zero-ohm resistors (R2/R44/R45/R48), removing R13, and installing R34 to pull SNSP2 to AVDD. In this mode, only rail 1's control loop remains active, enabling up to 16A total output current with synchronized phase operation - verified in the official EV kit documentation and schematic.

What input and output connections does the MAX20828TEVKIT# provide?

The MAX20828TEVKIT# uses banana jacks (J5/J8) for main input voltage (2.7V–16V), edge connectors (J12/J13) for output loads up to 8A per rail, and dedicated test points (TP5/TP6 for VIN, J2/J3 for VOUT1/VOUT2) for precision measurement. Optional external 3.3V bias is supported via J32/J33 with jumper J34 installed.

How is output voltage configured on the MAX20828TEVKIT#?

The MAX20828TEVKIT# ships preset to 1V on rail 1 and 1.8V on rail 2, achieved using resistor divider networks tied to the MAX20828T's 0.5V internal reference. Output voltage is calculated as VOUT = 0.5V × (1 + RFB1/RFB2); users can modify RFB1/RFB2 values to set any output between 0.5V and 5.8V per rail.

Does the MAX20828TEVKIT# support bode plot analysis?

Yes, the MAX20828TEVKIT# includes dedicated 10Ω injection resistors and matched test point pairs (TP13/TP14 for VOUT1, TP28/TP16 for VOUT2) to perform small-signal bode plot measurements. This allows direct loop gain and phase margin assessment - a critical capability for stability validation in regulated power supply designs using the MAX20828T.
