Quick Start

Recommended Equipment

• MAX17501HEVkit

• 4.5Vto60V,1ADCinputpowersupply

• Loadcapableofsinking500mA

• Digitalvoltmeter(DVM)

• Functiongenerator

Procedure

The EV kit is fully assembled and tested. Follow the

stepsbelowtoverifytheboardoperation.Caution: Do

not turn on power supply until all connections are

completed.

1) Setthepowersupplyatavoltagebetween4.5Vand

60V.Disablethepowersupply.

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 termi-

nal 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) Enabletheload.

7) Verify that the DVM displays the expected voltage.

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

stepsbelow:

1) Remove resistors R1 and R2 and the jumper con-

nected 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

between4.5Vand60V.

3) Connect the function generator output to the EN/

UVLO test loop.

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

old 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.

Detailed Description of Hardware

The MMAX17501H EV kit provides a proven design to

evaluate the MAX17501H high-efficiency, high-voltage,

synchronous step-down DC-DC converter in a TDFN

package. The EV kit generates 2.5V at load currents

up to 500mA from a 4.5V to 60V input supply. The EV

kit features a 300kHz fixed switching frequency for

optimum efficiency and component size. The EV kit fea-

tures a forced-PWM control scheme that provides con-

stant switching frequency operation at all load and line

conditions.
