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.
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.
