MAX8515 Evaluation Kit  
General Description  
Features  
The MAX8515 evaluation kit (EV kit) is a fully assembled  
and tested surface-mount circuit board that demon-  
strates the capability of the MAX8515A shunt regulator  
in a voltage-regulation circuit and the MAX8515 shunt  
regulator in an overvoltage protection (OVP) circuit for  
isolated DC-to-DC converters.  
o Isolated Voltage Regulation Feedback Circuit—  
Set to 0.8V Threshold  
o Isolated OVP Circuit—Set to 1V Threshold  
o Adjustable Output-Voltage Thresholds  
o Galvanically Isolated Input and Output Grounds  
o Surface-Mount Components  
The EV kit circuit is designed to operate from an input  
voltage supply with a nominal output of 8V and an output  
voltage range of 6V to 10V. The input voltage can be  
adjusted from 1.8V to 18V by replacing circuit compo-  
nents. The voltage-regulation circuit and the OVP circuit  
have their thresholds set to 0.8V and 1V, respectively.  
The thresholds can be adjusted by replacing feedback  
resistors on the circuit board.  
o Fully Assembled and Tested
