Product Overview
LTC®7803 is a high performance synchronous step-down DC/DC switching regulator controller with spread spectrum that drives an all N-channel power MOSFET stage. A constant frequency current mode architecture allows a phase-lockable switching frequency of up to 3MHz. The very low no-load quiescent current extends operating runtime in battery powered systems. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. The MODE pin selects among Burst Mode operation, pulse-skipping mode, or continuous inductor current mode at light loads. The LTC7803 additionally features spread spectrum operation which significantly reduces the peak radiated and conducted noise on both the input and output supplies, making it easier to comply with electromagnetic interference (EMI) standards. Typical applications are automotive and transportation, industrial, military/avionics, telecommunications.
