LTC7813MPUH#TRPBF Product Details
The LTC7813MPUH#TRPBF is a high performance synchronous Boost+Buck DC/DC switching regulator controller that drives all N-channel power MOSFET stages. It contains independent step-up (boost) and step-down (buck) controllers that can regulate two separate outputs or be cascaded to regulate an output voltage from an input voltage that can be above, below, or equal to the output voltage. The LTC7813MPUH#TRPBF operates from a wide 4.5V to 60V input supply range. When biased from the output of the boost regulator, the LTC7813MPUH#TRPBF can operate from an input supply as low as 2.2V after start-up. The 34μA no-load quiescent current (both channels on) extends operating runtime in battery-powered systems.
Unlike conventional buck-boost regulators, the LTC7813’s cascaded Boost+Buck solution has continuous, nonpulsating, input and output currents, substantially reducing voltage ripple and EMI. The LTC7813MPUH#TRPBF has independent feedback and compensation points for the boost and buck regulation loops, enabling a fast output transient response that can be externally optimized.
