A type of protection circuit where the output current decreases as the overload increases. The output current reaches a minimum as the load approaches a short-circuit condition.
An overcurrent protection circuit where the output current decreases with increasing overload, reducing the stress on SMPS components.
A special type of current limiting used in linear power supplies, which reduces the current through the supply's regulator to a low value under short circuited load conditions in order to protect the series pass transistor from excessive power dissipation and possible destruction.
A power supply output protection circuit whereby the output current decreases with increasing overload, reaching a minimum at short circuit. This minimizes internal power dissipation under overload conditions. Foldback current limiting is normally used with linear regulators and is not necessary with switching regulators.
