Abstract
The under voltage lockout circuit disclosed herein is useful in a switching mode power supply of the type which, in operation, powers its own regulator circuitry. The lockout circuit operates to inhibit energization of the power supply, including its own regulator, until a voltage reference is established which can control the operation of a comparator which monitors the supply voltage available to the regulator circuitry.
