LTC3875-Slide8

In summary, the LTC3875 is a dual output, current mode synchronous, step-down DC/DC controller that drives all N-channel synchronous power MOSFET stages. It employs a unique architecture which enhances the signal-to-noise ratio of the current sense signal, allowing the use of very low DCR power inductors to maximize the efficiency in high current applications. This feature also reduces the switching jitter commonly found in low DCR applications. The LTC3875 features two high speed remote sense differential amplifiers, programmable current sense limits from 10mV to 30mV, and DCR temperature compensation to limit the maximum output current precisely over temperature.
