EV Kit-Specific Component List

Component Suppliers

Quick Start

Recommended Equipment

• MAX17501B or MAX17501F EV kit

• 6V to 60V, 1A DC input power supply

• Load capable of sinking 500mA

• Digital voltmeter (DVM)

• Function generator

Procedure

The EV kit is fully assembled and tested. Follow the steps

below to verify the board operation. Caution: Do not turn

on power supply until all connections are completed.

1) Set the power supply at a voltage between 6V and 60V.

Disable the power supply.

2) Connect the positive terminal of the power supply to the

VIN PCB pad and the negative terminal to the nearest

PGND PCB pad. Connect the positive terminal of the

500mA load to the VOUT PCB pad and the negative

terminal to the nearest PGND PCB pad.

3) Connect the DVM across the VOUT PCB pad and the

nearest PGND PCB pad.

4) Verify that a shunt is installed across pins 1-2 on jumper

JU1.

5) Turn on the DC power supply.

6) Enable the load.

7) Verify that the DVM displays the expected voltage.

To turn-on/off the part from EN/UVLO, follow the steps

below:

1) Remove resistors R1 and R2 and the jumper installed

across pins 1-2 on jumper JU1.

2) Connect the power supply to the EV kit and turn on

the power supply. Set the power supply at a voltage

between 6V and 60V.

3) Connect the function generator output to the

EN/UVLO test loop.

4) EN/UVLO rising threshold is 1.24V and falling threshold

is 1.11V. Make sure that the voltage-high and voltage-

low levels of the function generator output are greater

than 1.24V and less than 1.11V, respectively.

5) While powering down the EV kits, first disconnect the

function generator output from the EN/UVLO test loop

and then turn off the DC power supply.

Care should be taken in board layout and systems wir-

ing to prevent violation of the absolute maximum rating of

the FB/VO pin under short-circuit conditions. Under such

conditions, it is possible for the ceramic output capacitor to

oscillate with the board or wiring inductance between the
