Analog Devices Inc./Maxim Integrated MAX20049EVKIT#

Overview

MAX20049EVKIT# from Maxim Integrated is a fully assembled and tested evaluation kit for the MAX20049 quad power supply IC, designed to validate its operation as a dual high-voltage step-down converter with dual LDOs in automotive camera module applications. It delivers four regulated outputs (3.8V/500mA, 1.8V/500mA, 3.3V/100mA, 1.2V/400mA) from a single 2.7V–18V input, featuring PGOOD monitoring, configurable LDOIN3 sourcing via jumper JU1, and preprogrammed factory-set voltages.

For engineers reviewing the MAX20049EVKIT# datasheet, MAX20049EVKIT# pinout, MAX20049EVKIT# application, or MAX20049EVKIT# equivalent, this kit enables rapid validation of voltage sequencing, load regulation, PSRR performance, and flexible power-tree configuration for automotive vision systems requiring compact, high-PSRR multi-rail supplies.

Technical Context

The MAX20049EVKIT# implements the complete reference design for the MAX20049ATEA/VY+ IC, supporting simultaneous evaluation of two 18V-input, 500mA buck converters (OUT1, OUT2) and two LDOs - a high-PSRR/low-noise 3.3V/100mA LDO3 powered from either OUT1, OUT2, or battery via JU1, and a 1.2V/400mA LDO4 with low-input-voltage operation. All outputs are preconfigured and factory-trimmed.

Hardware-level configurability includes resistor-based SUP1/SUP2 selection (R4/R5), PGOOD test point for combined regulation status of all four rails, and proven PCB layout optimized for EMI suppression and thermal management in space-constrained automotive modules.

FAQ

What is the primary function of the MAX20049EVKIT#?

The MAX20049EVKIT# is an evaluation kit that validates the full functionality of the MAX20049 quad power supply IC. It provides immediate access to all four regulated outputs (3.8V, 1.8V, 3.3V, 1.2V), supports configurable LDO3 input sourcing via jumper JU1, and includes PGOOD monitoring - allowing engineers to verify voltage accuracy, load regulation, sequencing, and noise performance without custom board design. The MAX20049EVKIT# is factory-assembled and tested for out-of-box validation.

Does the MAX20049EVKIT# support different output voltage configurations?

The MAX20049EVKIT# ships with factory-programmed output voltages: OUT1 = 3.8V, OUT2 = 1.8V, OUT3 = 3.3V, and OUT4 = 1.2V. These values are fixed on the evaluation board and not user-adjustable via resistors or pins. Custom voltage options require contacting Maxim (Analog Devices) for alternate configured boards or engineering samples of the MAX20049 IC itself - the MAX20049EVKIT# does not support field reprogramming of output voltages.

How is LDO3 powered on the MAX20049EVKIT# by default?

By default, jumper JU1 is installed in position 1–4, routing OUT1 (3.8V) to the LDOIN3 input pin. This configuration leverages the high-PSRR, low-noise characteristics of the MAX20049's LDO3 stage while minimizing noise coupling from other rails. Alternative configurations - such as powering LDO3 from OUT2 or directly from battery - are supported by moving JU1 to positions 1–2 or 1–3, respectively, as documented in Table 2 of the MAX20049EVKIT# user guide.

Can the MAX20049EVKIT# be used to evaluate load transient response?

Yes, the MAX20049EVKIT# supports load transient testing via dedicated test points (OUT1–OUT4, GNDx) and includes provisions for connecting electronic loads up to 500mA on buck outputs and 400mA on LDO4. The board's low-inductance layout, ceramic capacitor selection (e.g., C1/C2 = 22µF X6S), and accessible LX nodes enable accurate measurement of voltage deviation, recovery time, and stability under dynamic loading - critical for validating performance in automotive camera startup and mode-switching scenarios.

Is the MAX20049EVKIT# RoHS compliant and automotive qualified?

Yes, the MAX20049EVKIT# is RoHS compliant (denoted by # symbol in part number) and evaluates the MAX20049ATEA/VY+, which is specified for automotive temperature range (−40°C to +125°C) and AEC-Q100 qualified. The evaluation kit uses automotive-grade components including TDK and Murata MLCCs, Vishay precision resistors, and TDK shielded inductors - ensuring representative performance and reliability for production deployment in automotive vision systems.
