Patent number: 12381483Abstract: Load disconnect techniques for boost converters. In an example, a power converter includes a driver circuit, a control circuit, and a comparator circuit. During normal boost operation (VIN<VOUT), the comparator circuit disables the control circuit and enables the driver circuit, which in turn fully turns on a high-side switching element during high-side on-phase. In contrast, during start-up operation or an output short-to-ground condition (VIN?VOUT), the comparator circuit disables the driver circuit and enables the control circuit, which in turn controls the gate voltage of the high-side switching element, so the current through the switching element is regulated, and the switching node voltage is regulated to about a threshold voltage higher than VIN. In this manner, the comparator circuit controls the driver circuit and the control circuit, which in turn allow the boost converter to operate in a normal fashion even when VIN is higher than VOUT.Type: GrantFiled: January 3, 2023Date of Patent: August 5, 2025Assignee: TEXAS INSTRUMENTS INCORPORATEDInventor: Jian Liang
