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
