Analog Devices Inc./Maxim Integrated MAX20012EVKIT#

Overview

MAX20012EVKIT# from Maxim Integrated is an evaluation kit designed to demonstrate the MAX20012B automotive dual-channel step-down converter IC. It supports 3V–5.5V input, delivers 0.98V/24A on OUT1 and 0.95V/12A on OUT2, and features I²C-controlled output voltage (0.5V–1.5875V), 2.2MHz switching, ±2% output accuracy, and differential remote sensing for precision regulation in ADAS and infotainment power rails.

For engineers reviewing the MAX20012EVKIT# datasheet, MAX20012EVKIT# pinout, MAX20012EVKIT# application, or MAX20012EVKIT# equivalent, this board enables rapid validation of MAX20012B's dual-phase buck performance, I²C programmability, power-good signaling, synchronization capability, and thermal behavior under high-current automotive loads.

Technical Context

The MAX20012EVKIT# implements the MAX20012B IC in a fully assembled, production-ready PCB layout optimized for low-noise, high-efficiency automotive power delivery. It supports three operating modes - current-mode PWM, forced-PWM, and skip mode - and includes hardware-configurable enable (J4/J5), SYNC I/O selection (SO[1:0]), and I²C slave address setting (J6).

Hardware-level functions include differential remote voltage sensing at OUT1/OUT2, open-drain PGOOD assertion with UV/OV thresholds and 220μs delay after soft-start or DVS slewing, and configurable single-phase operation for OUT1 via component rework (L3 removal and R33→R34 resistor relocation).

FAQ

What does the MAX20012EVKIT# evaluate?

The MAX20012EVKIT# evaluates the MAX20012B - a dual-channel, AEC-Q100 qualified automotive step-down converter IC. It provides full hardware implementation including input filtering, power stages, feedback networks, I²C interface, and PGOOD monitoring. The board is preconfigured to deliver 0.98V/24A and 0.95V/12A, enabling immediate functional testing without soldering or configuration.

Does the MAX20012EVKIT# support I²C programming?

Yes, the MAX20012EVKIT# supports full I²C control of the MAX20012B IC via SDA/SCL test points and jumper J6 for slave address selection (ADDR = 0 or 1). Users can dynamically adjust output voltages between 0.5V and 1.5875V, configure operation modes, read status registers, and monitor faults - all using standard I²C commands as defined in the MAX20012B datasheet.

How is enable/shutdown controlled on the MAX20012EVKIT#?

Enable/shutdown is controlled via jumpers J4 (EN1) and J5 (EN2). Shunting pins 1–2 enables each output; shunting pins 2–3 disables it. When both are grounded, the MAX20012B enters shutdown mode drawing only 5µA typical quiescent current. This hardware-level control allows independent sequencing and fault isolation during system validation.

What is the purpose of the SYNC connector on the MAX20012EVKIT#?

The SYNC connector on the MAX20012EVKIT# allows synchronization of the MAX20012B's switching frequency to an external clock or enables it to drive other synchronized converters. Its function (input or output) is set by SO[1:0] bits in the IC's register map. This feature reduces beat frequencies and improves EMI performance in multi-rail automotive power systems.

Is the MAX20012EVKIT# fully assembled and tested?

Yes, the MAX20012EVKIT# is fully assembled and factory-tested. It includes all critical components - Vishay SiS452DN MOSFETs, MAX15492 gate drivers, IHLP2020BZ inductors, and X7R ceramic capacitors - and ships with verified PCB layout, thermal performance, and electrical functionality. No assembly or calibration is required before initial power-up and load testing.
