The 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.
The LTC3867 features a precision 0.6V reference and can regulate output voltages up to 14V from a wide 4V to 38V input supply range. The LTC3867 includes a high speed differential remote sense amplifier. Burst Mode® operation, continuous and pulse-skipping modes are supported. The LTC3867 is available in a 24-lead (4mm × 4mm) QFN package.
