SMART COMPENSATION FOR BUCK CONVERTERS IN DISCONTINUOUS CONDUCTION MODE - A simplified explanation of the abstract
This abstract first appeared for US patent application 17972811 titled 'SMART COMPENSATION FOR BUCK CONVERTERS IN DISCONTINUOUS CONDUCTION MODE
Simplified Explanation
A buck converter described in the patent application includes various components such as high-side and low-side N-FETs, a P-FET, a capacitor, and a FET driver. The FET driver can operate in either continuous current mode or discontinuous current mode. During the first phase of the discontinuous current mode, the gate voltage on the N-FET is equalized to the source voltage to turn on the N-FET, while the high output voltage of the FET driver turns on the high-side P-FET.

Original Abstract Submitted
A buck converter includes a high-side N-FET, a low-side N-FET, a P-FET, a between a gate terminal and a source terminal of the P-FET, aa capacitor, and a FET driver. The FET driver operates in a selectable one of a continuous current mode and a discontinuous current mode. In a first phase of the discontinuous current mode, a gate voltage on the gate terminal the N-FET equalizes to a source voltage on the source terminal of the N-FET to turn on the first N-FET. A high output voltage on a high-side output of the FET driver is high enough to overcome a threshold voltage of a body diode of the first P-FET to provide the high output voltage minus a threshold voltage to the gate terminal of the high-side P-FET to turn on the high-side P-FET.
