Analog Devices Inc./Maxim Integrated MAX20019EVKIT#

Overview

MAX20019EVKIT# from Maxim Integrated is an evaluation kit for the MAX20019/MAX20020 dual synchronous step-down DC-DC converters, designed to demonstrate high-efficiency power conversion in automotive point-of-load applications. It delivers regulated 3.3V at 500mA (OUT1) from a 3.5V–16V input and steps that down further to 1.8V at 500mA (OUT2), operating at 3.2MHz with all-ceramic output filtering.

For engineers reviewing the MAX20019EVKIT# datasheet, MAX20019EVKIT# pinout, MAX20019EVKIT# application, or MAX20019EVKIT# equivalent, this kit enables rapid validation of dual-output power architecture, switching frequency impact on component count, ceramic capacitor sizing, and jumper-controlled enable sequencing for automotive camera modules.

Technical Context

The MAX20019EVKIT# implements the MAX20019 IC's dual-buck topology with integrated high-side and low-side MOSFETs per channel. OUT1 accepts 3.5V–16V input and regulates to fixed 3.3V; OUT2 accepts the OUT1 output as its input and regulates to fixed 1.8V - both delivering up to 500mA with 3.2MHz constant-frequency PWM control.

It features independent ON/OFF jumpers for each output, uses only ceramic capacitors due to high switching frequency, and incorporates a proven PCB layout optimized for EMI performance and thermal management in space-constrained automotive environments.

FAQ

What is the primary function of the MAX20019EVKIT#?

The MAX20019EVKIT# is an evaluation kit that demonstrates the dual-output operation of the MAX20019 IC. It provides two regulated outputs - 3.3V at 500mA (OUT1) and 1.8V at 500mA (OUT2) - from a single 3.5V–16V input. The MAX20019EVKIT# enables hardware validation of power sequencing, efficiency, thermal behavior, and EMI performance before integrating the MAX20019 into final automotive designs.

Does the MAX20019EVKIT# support adjustable output voltages?

No, the MAX20019EVKIT# implements fixed-output configurations only: OUT1 is factory-set to 3.3V and OUT2 to 1.8V, matching the default settings of the MAX20019 IC. These voltages are not user-adjustable via resistors or pins on the EV kit. For variable outputs, designers must refer to the MAX20019 datasheet and consider custom board implementation using feedback resistor networks.

Can the MAX20019EVKIT# be used to evaluate the MAX20020 as well?

Yes, the MAX20019EVKIT# is explicitly designed to evaluate both the MAX20019 and MAX20020 ICs. Though the MAX20020 offers different fixed output combinations (e.g., 5V/1.8V), the EV kit's layout, component selection, and jumper controls accommodate either device with no hardware modification required - enabling side-by-side comparison of performance and thermal characteristics.

What type of input power source is recommended for the MAX20019EVKIT#?

A clean, current-limited DC supply delivering 3.5V to 16V is recommended for the MAX20019EVKIT#. Automotive battery simulators or lab power supplies with overvoltage/overcurrent protection are ideal. Input ripple should be <50mVpp, and the supply must sustain ≥700mA peak current to handle startup and load transients without droop affecting the MAX20019EVKIT#'s regulation stability.

Are test points and measurement interfaces provided on the MAX20019EVKIT#?

Yes, the MAX20019EVKIT# includes dedicated test points for VIN, OUT1, OUT2, PG1, PG2, and ground, along with solder pads for optional input/output capacitance changes. These facilitate oscilloscope probing, efficiency measurements, and transient response analysis without soldering or board modification - critical for validating the MAX20019EVKIT# under real-world load steps and thermal conditions.
