Typical Application for LTC3855 - Dual, Multiphase Synchronous DC/DC Controller with Differential Remote Sense

Typical Application for LTC3855 - Dual, Multiphase Synchronous DC/DC Controller with Differential Remote Sense. The LTC3855 is a dual Poly-Phase current mode synchronous step-down switching regulator controller that drives all N-channel power MOSFET stages. It includes a high speed differential remote sense amplifier. The maximum current sense voltage is programmable for either 30mV, 50mV or 75mV, allowing the use of either the inductor DCR or a discrete sense resistor as the sensing element
