Output protections are implemented in DC-DC converters to prevent damage to the converter or attached loads. One type of protection is for short circuits. Short circuit protection kicks in and shuts down the device when a short circuit condition is created. Typically once the short is removed, the device will recover to normal operation. Over voltage protection similarly shuts down the DC-DC converter when its voltage exceeds a specified range. Over current or over load protection is a feature that limits the output current so the DC-DC converter will not be damaged. Finally, under voltage lock out is a protection where the device shuts down when the input voltage drops below a certain level. Most DC-DC converters incorporate most if not all of these types of protections.
