Product details
Overview
MAX20038EVKIT# from Maxim Integrated is an evaluation kit for the MAX20038 automotive synchronous step-down DC-DC converter with integrated USB port detection, host-charger emulation, and cable-drop compensation. It delivers 3A continuous output at 105°C, operates up to 28V input (40V load dump protected), and supports I²C-configurable switching frequencies from 275kHz to 2.2MHz.
For engineers reviewing the MAX20038EVKIT# datasheet, MAX20038EVKIT# pinout, MAX20038EVKIT# application, or MAX20038EVKIT# equivalent, this kit enables rapid validation of USB-compliant charging behavior, real-time fault diagnostics via I²C, and voltage compensation across captive automotive cables using the onboard MAX20038 IC and tuned data-line components.
Technical Context
The MAX20038EVKIT# implements the MAX20038 IC in a fully assembled, production-ready PCB layout optimized for USB BC1.2, Apple, and YD/T 1591-2009 charge detection. It integrates high-side current sensing, programmable VOUT adjustment, and I²C-accessible ADC reporting of output voltage and current.
Designed for automotive infotainment and telematics power rails, the kit demonstrates the IC's 2.2MHz default switching frequency, 3m USB cable compensation capability, and data-line tuning for optimal eye diagram performance - validated per Figure 19 of the MAX20037/MAX20038 datasheet.

FAQ
What is the primary function of the MAX20038EVKIT#?
The MAX20038EVKIT# is a fully assembled evaluation kit that demonstrates the MAX20038 IC's capabilities as an automotive-grade, 3A synchronous step-down converter with integrated USB battery charging detection (BC1.2, Apple, YD/T 1591), host-charger emulation, and automatic USB voltage adjustment for captive cable drop compensation. It enables functional validation and system integration testing.
Does the MAX20038EVKIT# include the MAX20038 IC with I²C interface enabled?
Yes, the MAX20038EVKIT# is populated with an I²C-enabled version of the MAX20038 IC. This allows full access to configuration registers, real-time fault diagnostics, and ADC-reported output voltage and current values using the included MINIQUSB command module and GUI software.
Can the MAX20038EVKIT# demonstrate USB cable compensation?
Yes, the MAX20038EVKIT# includes a 3m USB cable and factory-tuned data-line components to demonstrate the MAX20038's automatic USB voltage adjustment feature. This compensates for IR drop in long captive cables typical in automotive installations, maintaining regulated 5V at the connector under load.
What USB charging standards does the MAX20038EVKIT# support through the MAX20038 IC?
The MAX20038EVKIT# supports USB-IF Battery Charging Specification v1.2 (CDP and DCP modes), Apple iPod/iPhone/iPad 2.4A and 1.0A termination profiles, and China's YD/T 1591-2009 standard - all implemented directly by the onboard MAX20038 IC without external detection circuitry.
Is the MAX20038EVKIT# preconfigured for a specific switching frequency?
Yes, the MAX20038EVKIT# is configured for 2.2MHz operation out-of-box. This enables use of smaller external passive components and reduces EMI concerns in space-constrained automotive layouts, while remaining within the MAX20038's full 275kHz–2.2MHz programmable range.
