Linear introduces a current-mode synchronous step-down DC/DC controller

Linear Technology Corp. introduces the LTC3875, a dual output current-mode synchronous step-down DC/DC controller that enables the use of very low DC resistance (DCR) power inductors by using a novel DCR sensing architecture that enhances the signal-to-noise ratio of the current sense signal. Power inductor DCR, as low as 0.2 milliohms can be used without a sense resistor to maximize converter efficiency and increase power density. This new DCR sensing technique dramatically reduces the switching jitter normally associated with low DCR sensing applications.
