LTC3855 2.5V, 15A and 1.8V, 15A Supply with NTC Temperature Compensated DCR Sensing, fSW = 350kHz

2.5V, 15A and 1.8V, 15A Supply with NTC Temperature Compensated DCR Sensing, fSW = 350kHz

The LTC3855 is a dual PolyPhase 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.
