Abstract
Methods, systems, and apparatus to facilitate high side control of a switching power converter are disclosed. An example apparatus includes a latch including a first node coupled to a first source of a first switch and an output coupled to a first gate of the first switch; a first diode coupled to the first node and a second node; a second diode coupled to the second node and ground; a second switch coupled to a voltage source and the second node; and a third switch including a third gate coupled to the second switch, a third source coupled to the second node, and a third drain coupled to the latch.
