一种用于低压单片多相Buck变换器的紧凑且精确的自减法RLG电流传感器

This article introduces a novel self-subtracted RLG current sensor (SSRLGCS) for a low-voltage monolithic multiphase buck converter. The sensor subtracts the product of the duty cycle and VIN voltage from VLX voltage with a simple RC filter to obtain the inductor current information with a sensing gain equal to RLG. By adjusting the RC filter corner frequency, this sensor effectively extracts eith...
