APPLICATION NOTE 2160
Using the MAX8515 Shunt Regulator In Output Overvoltage Sensing
Applications for DC-DC Converters

Output overvoltage protection is a critical feature for DC-DC converters in order to protect sensitive loads from
permanent damage. The basic requirements for an overvoltage protection (OVP) circuit are precise sensing of
the output voltage condition and fast activation of the shutdown circuit. The MAX8515 shunt regulators are
excellent candidates for implementing this function in DC-DC converters.
