The LTC
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 DC resistance power inductors to maximize efficiency in high current applications.
Key features include two high speed remote sense differential amplifiers, programmable current sense limits from 10mV to 30mV, and DCR temperature compensation. The device supports a wide input voltage range of 4.5V to 38V and provides an output voltage range of 0.6V to 3.5V with low DCR sensing.
