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4.5V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 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) Enabletheload.
7) Verify that the DVM displays the expected voltage.
To turn-on/turn-off the part from EN/UVLO, follow the
stepsbelow:
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
between4.5Vand60V.
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.
Note: Indicate that you are using the MAX17501 when contacting these component suppliers.
