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.

The MAX8515 shunt regulators are excellent candidates for implementing this function in DC-DC converters. These devices offer the advantages of combining an accurate 0.6V reference, comparator and an output drive stage in space saving SC70 and THIN SOT23 packages (Figure 1).
