Title:
BUCK-BOOST CONVERTER POWER SUPPLY WITH DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2018/023354
Kind Code:
A1
Abstract:
A power supply (50) includes a first supply input node (38) and a second supply input node (40), a supply output node (42), first and second switch circuits (24, 28), a filter circuit (32), and a drive circuit (54). The first and second supply input nodes are respectively configured to receive first and second input voltages, and the supply output node is configured to provide an output voltage. The first switch circuit (24) has a first conduction node coupled to the first supply input node, a second conduction node, and a control node configured to receive a first control signal (S 1). The filter circuit has a first node (60) coupled to the second conduction node and has a second node. The second switch circuit (28) has a first conduction node coupled to the second node of the filter circuit, a second conduction node coupled to the second supply input node, and a control node. The drive circuit has an input node (58) coupled to one of the control node of the first switch circuit and the first node of the filter circuit, and has an output node (62) coupled to the control node of the second switch circuit.
