ABSTRACT:
A start-up circuit for a switching mode power supply is described. The circuit has an initial power supply means for initiating pulses from a pulse generator. Latches are used once a stable output current is established to disengage the initial power supply. Thus, the pulse generator and the switching transistor are protected from power surges.
