Abstract
A buck-boost switch mode regulated power supply using a burst circuit topology includes a detection circuit to sense overcurrent in the high side connected power transistor. This causes the flip flop to flip which turns off the transistor. A comparator connected to the output voltage detects when the output voltage falls below the threshold value of the comparator and sends a signal to the flip flop which is reset upon the next pulse of a pulsed reset signal. When the flip flop is reset, the high side power transistor is turned back on.
