MAX17681 Evaluation Kit
Evaluates: MAX17681 for Isolated
+24V Output Configuration
General Description
The MAX17681EVKITF is a fully assembled and tested
circuit board that demonstrates the performance of the
The EV kit operates over a wide input-voltage range of
17V to 36V and uses primary-side feedback to regulate
+24V at 100mA, with ±10% output voltage regulation. The
The EV kit comes installed with the MAX17681 in a 10-pin
(3mm x 2mm) TDFN package.

Quick Start
Recommended Equipment
● One 15V–60V DC, 0.5A power supply
● One resistive load 100mA sink capacity
● Two digital multimeters (DMM)
Caution: Do not turn on the power supply until all
connections are completed.
Procedure
The EV kit comes with the default output configuration
programmed to +24V.
Test Procedure for +7V Output
1) Verify that J1 is open.
2) Verify that R7 is not installed.
3) Set the power supply output to 24V. Disable the
power supply.
4) Connect the positive terminal of the power supply
to the V_IN PCB pad and the negative terminal to the
nearest PGND PCB pad. Connect a 100mA resistive
load across the +24V PCB pad and the GND0 PCB pad.
5)
the +24V PCB pad and the nearest GND0 PCB pad.
6) Enable the input power supply.
7) Verify that output voltage is at +24V (with allowable
tolerance of ±10%) with respect to GND0.
8) If required, vary the input voltage from 17V to 36V, and the
load current from 0mA to 100mA and verify that output voltage
is at +24V (with allowable tolerance of ±10%).
