LTC3875-Slide2

The LTC3875 is a high performance, 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, enhancing the signal-to-noise ratio of the current sense signal. Power inductor DCRs as low as 0.2 mΩ 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 when a current mode controller is employed.
