ANALOG DEVICES INC. LTC7804 Low IQ Synchronous Boost Controller
The LTC7804 is a high-performance synchronous boost DC/DC switching regulator controller that drives an all N-channel power MOSFET stage.
Synchronous rectification increases efficiency, reduces power losses, and eases thermal requirements. A constant frequency current mode architecture allows a phase-lockable switching frequency of up to 3MHz.
The LTC7804 operates from a wide 4.5V to 40V input supply range. When biased from the boost converter output , the LTC7804 can operate from an input supply as low as 1V after startup.
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, and continuous inductor current mode at light loads.
A typical sensing circuit can be accomplished using either a discrete resistor RSENSE or by sensing the voltage drop across the inductor DC resistance in applications requiring the highest possible efficiency at high load currents.
The LTC7804 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 standards. Finally, the LTC7804 is offered in thermally enhanced 16-Pin QFN and MSOP Packages for a space efficient design.
