MAX17541G 5V Output
Evaluation Kit
Evaluates: MAX17541G in 5V
Output-Voltage Application
General Description
The MAX17541G 5V Output EV kit provides a proven
design to evaluate the MAX17541G 5V high-efficiency,
high-voltage, synchronous step-down DC-DC converter.
The EV kit generates 5V at load currents up to 500mA
from a 6V to 42V input supply. The EV kit features a
600kHz fixed switching frequency for optimum efficiency
and component size. The EV kit features a forced-PWM
control scheme that provides constant switching-frequency
operation at all load and line conditions.

Quick Start
Recommended Equipment
●● MAX17541G 5V Output EV kit
●● 6V to 42V, 2A 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
42V. 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) Turn on the DC power supply.
5) Enable the load.
6) Verify that the DVM displays 5V.
To turn-on/off the part from EN/UVLO, follow the steps
below:
1) Connect the power supply to the EV kit and turn on
the power supply. Set the power supply at a voltage
between 6V and 42V.
2) Connect the function generator output to the EN/UVLO
test loop.
3) 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.
4) While powering down the EV kit, first disconnect the
function generator output from the EN/UVLO test
loop and then turn off the DC power supply.
