MAX20333 Evaluation Kit  
General Description  
Quick Start  
The MAX20333 evaluation kit (EV kit) is a fully assembled  
and tested circuit board that demonstrates the MAX20333  
0.2A to 4.75A adjustable current-limit switch device. The  
EV kit comes with the MAX20333ENL+ installed. The EV  
kit board can also be used to evaluate MAX20333A/B/C/D/  
E/F/G/H/I/J/K/L/M/N.  
Required Equipment  
MAX20333 EV kit  
9V Power Supply  
5V Power Supply  
Multimeter  
Load Box  
Features  
3.5V to 22V Operating Voltage Range  
Procedure  
(3.3V to 22V for MAX20333L/M/N)  
The EV kit is fully assembled and tested. Follow the steps  
below to verify board operation:  
Output and Flag LED Reading  
Adjustable Current Limit Setting  
Adjustable Blanking Time (PBT version)  
Proven PCB Layout  
1) Connect 5V on V TP14.  
IO  
2) Connect 9V on INPUT TP5. Use the voltmeter to  
check that the OUT TP6 voltage is 9V.  
3) Connect the load box to OUT. Increase the load  
current and verify that the OUT voltage goes down  
when output current goes up to about 1A, and D3  
turns on (when overcurrent is in normal mode, FLAG  
is asserted).

4) Remove the output load. Cycle the INPUT power,  
verify D3 is off, and OUT voltage is 9V.  
Ordering Information appears at end of data sheet.  
5) Change JU3 to the 1–2 position. Connect the load  
box to OUT.  
6) Increase the load current and verify the OUT voltage  
goes down when output current goes up to about 2A,  
and D3 turns on (when overcurrent is in high current  
mode, FLAG is asserted).
