MAX16936 Evaluation Kit  
General Description  
Quick Start  
The MAX16936 evaluation kit (EV kit) demonstrates  
the MAX16936 high-voltage, current-mode step-down  
converter with low operating current. The EV kit operates  
over a wide 3.5V to 36V input range and the output is set  
for 5V at 2.5A.  
Required Equipment  
MAX16936 EV kit  
14V, 1A DC power supply  
Electronic load capable of 2.5A  
Digital voltmeter (DVM)  
The EV kit comes with the MAX16936RAUEA/V+ installed.  
Features  
Procedure  
Wide 3.5V to 36V Input Supply Range  
Forced-PWM or Skip-Mode Operation  
Programmable Switching Frequency  
Power-Good Output  
The EV kit is fully assembled and tested. Follow the steps  
below to verify board operation. Caution: Do not turn on  
supplies until all connections are made.  
1) Verify that jumpers JU1 and JU2 are in their default  
positions, as shown in Table 1 and Table 2.  
Proven PCB Layout  
2) Connect the power supply between the EXT_VBAT  
and nearest PGND test points.  
Fully Assembled and Tested  
3) Connect the 2.5A electronic load between the OUT  
and nearest PGND test points.  
4) Connect the DVM between the OUT and nearest  
PGND test points.  
5) Turn on the power supply.  
6) Enable the electronic load.  
Ordering Information appears at end of data sheet.  
7) Verify that the voltage at the OUT test point is approxi-  
mately 5V.
