MAX20406 Evaluation Kit

General Description

Quick Start

The MAX20406 evaluation kit (EV kit) provides a proven

design to evaluate the MAX20406 automotive 2.1MHz

synchronous buck converter with 10µA quiescent current.

The standard EV kit PCB comes with a MAX20406AFOB/

VY+ (2.1MHz, 3.3V) installed, as well as various test

points and jumpers for evaluation. The EV kit output volt-

age is ﬁxed and easily conﬁgured with minimum compo-

nent changes. The default EV kit is designed to deliver

up to 6A with input voltage 3V to 36V. Output voltage

quality can be monitored by observing the PGOOD signal.

The MAX20406 EV kit can also be used to evaluate the

MAX20404 and MAX20405.

Required Equipment

● MAX20406 EV Kit

● 36V, 6A Power Supply (PS)

● Appropriate Resistive Load, or an Electronic Load

that can Sink 6A

● Digital Multimeter (DMM)

● Oscilloscope

Procedure

The EV kit comes fully assembled and tested. Follow the

steps below to verify board operation:

1) Verify that all jumpers are in their default positions, as

shown in Table 1.

Beneﬁts and Features

● Input Supply Range from 3V to 36V

2) Connectthepositiveandnegativeterminalsofthepow-

er supply to the VSUP_FILTER and GND test pads,

respectively.

● Output Voltage: 3.3V/5V Fixed and Adjustable from

0.8 to 10V

● Delivers up to 6A

3) Set the power-supply voltage to 14V and current limit

to 6A.

● Frequency - Synchronization Input

● Enable Input

4) Turn on the power supply.

● Spread Spectrum Available

● Voltage Monitoring PGOOD Output Available

● Proven PCB Layout

5) Using the DMM, verify the VOUT is approximately

3.3V.

6) Verify that the switching frequency is 2.1MHz

(approx.) by monitoring the inductor switching voltage

with the oscilloscope.

● Fully Assembled and Tested

Ordering Information appears at end of data sheet.

Additional Evaluation

7) Connect the positive and negative terminals of the

electronic load to VOUT and GND3, respectively.

8) Set the electronic load to the desired current at or

below 6A or use an equivalent resistive load with an

appropriate power rating.

9) Adjust current limit on the power supply as necessary.

10) Turn on the power supply and electronic load.

11) Verify that voltage across the VOUT and GND3 is 3.3V.
