MAX25206 Evaluation Kit

Evaluates: MAX25206/8

General Description

Quick Start

The MAX25206 evaluation kit (EV kit) provides a proven

design to evaluate the MAX25206/8 automotive 2.2MHz

synchronous step-down controllers with 7µA I . The EV

Required Equipment

● MAX25206 EV Kit

● 3.5V to 60V, 7A power supply (power supply should

kit PCB comes with a MAX25206 IC installed, as well as

various test points and jumpers for evaluation. The EV kit

output voltage is fixed and is easily configured with mini-

mum component changes. The default EV kit is designed

to deliver up to 7A with input voltages from +3.5V to +60V

(MAX25206) and +70V (MAX25208), but can be config-

ured to deliver up to 20A. Output voltage quality can be

monitored by observing the PGOOD signal.

be capable of providing 7A at 3.5V input)

● 1 Digital multimeter (DMM)

● 1 Oscilloscope

● Electronic load capable of sinking 7A

Procedure

The MAX25206 EV kit is fully assembled and tested.

Follow the steps below to verify board operation:

Beneﬁts and Features

● +3.5V to +60V (MAX25206) and +70V (MAX25208)

1) Verify that all jumpers are in their default

conﬁgurations according to Table 1.

Input Supply Range

2) Connect the positive and negative terminals of the

power supply to SUP and GND1 test pads, respec-

tively.

● Output Voltage: 5V or 3.3V Fixed or Adjustable

between 0.7V to 20V

● Delivers up to 20A Output Current

● Frequency Synchronization Input

● Frequency Synchronization Output

● Spread-Spectrum Control

● Enable Input

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

to 10A.

4) Turn on the power supply.

5) Verify that OUT is approximately 5V using a digital

multimeter.

● Voltage-Monitoring PGOOD Output

● Proven PCB Layout

6) Verify that the switching frequency is approximately

2.2MHz by monitoring inductor switching voltage with

oscilloscope.

● Fully Assembled and Tested
