LTC3867EUF#PBF

LTC3867 is a current mode synchronous step-down switching regulator controller that drives all N-channel power MOSFET stages. Output voltage transient excursions are minimized by use of a nonlinear control architecture to eliminate clock latency issues. The maximum current sense voltage is programmable from 30mV to 75mV, allowing the use of either a discrete sense resistor or the inductor DCR as the sensing element. Programmable DCR temperature compensation allows constant current limit regardless of inductor temperature. Programmable inductor temperature-based thermal shutdown protects the power components from thermal stress. Soft recovery from output shorts or overcurrent minimizes output overshoot. It is used in applications such as automotive systems, telecom systems, industrial equipment, distributed DC power systems etc.
