Product details
Overview
MAX20003EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit designed to demonstrate the MAX20003ATPA/V+ high-voltage, current-mode step-down converter. It operates from 3.5V to 36V input, delivers 5V at 3A output, supports forced-PWM or skip-mode operation, features programmable switching frequency via resistor R4 (12.1kΩ), and includes power-good monitoring and spread-spectrum capability.
For engineers reviewing the MAX20003EVKIT# datasheet, MAX20003EVKIT# pinout, MAX20003EVKIT# application, or MAX20003EVKIT# equivalent, this board enables rapid validation of automotive-grade buck converter performance under wide-input-voltage conditions, transient load response, PGOOD timing behavior, and FSYNC synchronization with external clocks up to ±20% frequency deviation.
Technical Context
The MAX20003EVKIT# implements the MAX20003ATPA/V+ in a 20-pin TQFN-EP package with exposed pad thermal management. Its hardware supports configurable EN control (JU1), mode selection (forced-PWM/skip via JU2), spread-spectrum enable/disable (JU3), and PGOOD pull-up (JU4), all accessible via 3-pin or 2-pin shunt headers.
Key design elements include front-end filtering (C1–C4, L2), output capacitance (C7, C8 = 22µF each), feedback network (R1 = 20.0kΩ for 5V default), and FOSC programming (R4 = 12.1kΩ sets nominal switching frequency). The board provides test points for SUPSW, SUP, VOUT, PGOOD, and FSYNC to support bench-level characterization.

FAQ
What is the primary function of the MAX20003EVKIT#?
The MAX20003EVKIT# is an evaluation platform for the MAX20003ATPA/V+ buck converter. It enables functional verification, efficiency measurement, transient response analysis, and configuration testing-including EN control, mode selection, spread-spectrum enablement, and external clock synchronization-without requiring custom PCB development.
Does the MAX20003EVKIT# support adjustable output voltages?
Yes. The MAX20003EVKIT# defaults to 5V output via FB-to-BIAS connection, but supports 1V–10V outputs using an external resistive divider between OUT, FB, and AGND. The formula VOUT = VFB × (1 + R7/R8), where VFB = 1V, determines the required resistor values.
How is switching frequency configured on the MAX20003EVKIT#?
Switching frequency on the MAX20003EVKIT# is set by resistor R4 (FOSC-to-AGND). The default 12.1kΩ yields the nominal frequency; changing R4 to 73.2kΩ configures 400kHz operation, requiring corresponding updates to L1 (6.8µH), R1 (16.5kΩ), C10 (4700pF), and C11 (6.8pF).
Can the MAX20003EVKIT# operate in skip mode?
Yes. The MAX20003EVKIT# supports skip mode by moving the shunt on jumper JU2 to position 2–3, connecting the MODE pin to AGND. This reduces light-load quiescent current versus forced-PWM mode, improving efficiency at partial loads.
What test points are provided on the MAX20003EVKIT# for signal monitoring?
The MAX20003EVKIT# provides red test points for SUPSW, SUP, VOUT, and PGOOD, plus black PGND points. These allow direct probing of input switching node, input rail, regulated output, and power-good status without soldering or modification.
