Evaluate: MAX20004/MAX20006/MAX20008

MAX20006/MAX20008

Evaluation Kits

General Description

The MAX20006/MAX20008 evaluation kits (EV kits)

demonstrate the MAX20004/MAX20006/MAX20008 high-

voltage, current-mode, synchronous step-down convert-

ers with low operating current. The EV kits operate over a

wide 3.5V to 36V input range. The output is set for 5V in

the default configuration but can be adjusted between 1V

and 10V with appropriate components. The MAX20004/

MAX20006/MAX20008 current limit supports a nominal

output current of 4A/6A/8A, respectively.

The EV kit switching frequency is set for either 2.2MHz

(MAX20006EVKIT) or 400kHz (MAX20008EVKIT) in the

default configuration. The switching frequency is resistor

programmable between 220kHz and 2.2MHz and can be

synchronized to an external signal. The EV kits can be

set for fixed-frequency (PWM mode) or pulse-skipping

(SKIP mode) for light load efficiency through the provided

on-board jumper.

Quick Start

Required Equipment

● MAX20006/MAX20008 EV kit

● 14V, 4A DC power supply

● Electronic load capable of 8A

● Digital voltmeter (DVM)

Procedure

Each EV kit is fully assembled and tested. Follow the

steps below to verify board operation.

Caution: Do not

turn on supplies until all connections are made.

1) Verify that jumpers JU1–JU2 are in their default posi-

tions, as shown in Table 1.

2) Connect the 14V power supply between the VIN and

nearest GND input terminals on the EV kit.

3) Connect the electronic load between the VOUT and

nearest GND output terminals on the EV kit and set

for 6A (MAX20006EVKIT) or 8A (MAX20008EVKIT).

4) Connect the DVM between the VOUT and nearest

GND output terminals on the EV kit.

5) Turn on the power supply.

6) Enable the electronic load.

7) Verify that the voltage at VOUT is approximately 5V.
