Description
Sensing the inductor DCR voltage can be an accurate and lossless technique of obtaining current information in DC/DC regulators. The absence of a series current sense resistor permits high current and high efficiency designs at a lower cost and higher density. Inductor DCR sensing also allows continuous monitoring of the inductor current as opposed to MOSFET RDS(ON) sensing that usually samples th
