Abstract

Abstract The output control circuit includes: a first high side transistor 56 coupled to an output node 68; a second high side transistor 59 coupled in parallel with the first high side transistor 56; a first transmission gate 72 coupled between a control node of the first high side transistor 56 and a control node of the second high side transistor 59, the first transmission gate 72 is controlled by feedback from the output node 68; a first low side transistor 50 coupled to the output node 68; a second low side transistor 53 coupled in parallel with the first low side transistor 50; a second transmission gate 74 coupled between a control node of the first low side transistor 50 and a control node of the second low side transistor 53, the second transmission gate 74 is controlled by feedback from the output node 68.
