Analog Devices Inc./Maxim Integrated MAX20419EVKIT#

Overview

MAX20419EVKIT# from Maxim Integrated is an evaluation kit designed to demonstrate the MAX20419ATGB/V+ triple-output PMIC for automotive power management. It integrates a 5V/750mA synchronous boost converter (OUT1) and two 2A synchronous buck converters (2.3V OUT2, 1.25V OUT3), operating at 2.2MHz with all-ceramic output filtering-enabling compact ADAS and infotainment SoC power designs.

For engineers reviewing the MAX20419EVKIT# datasheet, MAX20419EVKIT# pinout, MAX20419EVKIT# application, or MAX20419EVKIT# equivalent, key selection considerations include input voltage range (3.0V–5.5V), programmable watchdog functionality, SYNC mode flexibility (FPWM/skip/external sync), individual active-low RESET outputs, and PV_OV input power-good monitoring.

Technical Context

The MAX20419EVKIT# implements the full functional interface of the MAX20419ATGB/V+ PMIC, including independent enable/control of three regulated outputs, real-time status feedback via three dedicated RESET_ signals, and a windowed watchdog timer configurable through I²C or hardware pins. Its 2.2MHz switching frequency enables use of 1µF–10µF ceramic capacitors without ferrite beads or electrolytics.

Power sequencing is supported via jumper-selectable on/off control per rail, while the SYNC input accepts external clock sources up to 4MHz or selects internal FPWM/skip modes. The PV_OV input monitors VIN with ±3.7% tolerance and asserts an open-drain signal when out-of-window.

FAQ

What is the primary function of the MAX20419EVKIT#?

The MAX20419EVKIT# is a fully assembled evaluation kit that demonstrates the MAX20419ATGB/V+ triple-output PMIC. It provides immediate hardware validation for the 5V boost and dual 2A buck regulators, enabling rapid power architecture testing for automotive SoCs without custom PCB development. The MAX20419EVKIT# includes jumpers, test points, and status indicators aligned to production-level implementation.

Does the MAX20419EVKIT# support external clock synchronization?

Yes, the MAX20419EVKIT# exposes the SYNC input pin, allowing users to force PWM mode, enable skip mode, or synchronize switching to an external clock source up to 4MHz. This capability is implemented directly from the MAX20419ATGB/V+ IC's native functionality and verified on the EV kit's PCB layout and firmware configuration.

How are output voltages configured on the MAX20419EVKIT#?

Output voltages on the MAX20419EVKIT# are fixed by onboard resistor dividers and match the nominal values specified for the MAX20419ATGB/V+: OUT1 = 5.0V, OUT2 = 1.25V, OUT3 = 2.3V. No user adjustment is required-these settings reflect the factory-programmed configuration of the MAX20419EVKIT# to validate the target PMIC's default power tree.

What does the PV_OV signal indicate on the MAX20419EVKIT#?

The PV_OV signal on the MAX20419EVKIT# is an active-low input power-good monitor tied to the MAX20419ATGB/V+'s internal comparator. It asserts when the input supply voltage deviates more than ±3.7% from its nominal value-providing real-time VIN supervision critical for automotive cold-crank and load-dump scenarios. The MAX20419EVKIT# routes this signal to a test point and LED indicator.

Is the MAX20419EVKIT# RoHS-compliant and qualified for automotive use?

Yes, the MAX20419EVKIT# uses only components qualified to AEC-Q200 standards where applicable and complies with RoHS Directive 2011/65/EU. Its PCB, connectors, and passive components are selected to meet automotive temperature range requirements (–40°C to +125°C ambient), consistent with the MAX20419ATGB/V+ PMIC's qualification profile.
