www.DataSheet4U.com FEATURES n n n n n n n n n n n n n n LTC3854 Small Footprint, Wide VIN Range Synchronous Step-Down Controller DESCRIPTION The LTC3854® is a high performance synchronous stepdown switching regulator controller that drives an all N-channel synchronous power MOSFET stage. The LTC3854 features a 400kHz constant frequency current mode architecture. The LTC3854 operates from a 4.5V to 38V (40V absolute maximum) input voltage range and regulates the output voltage from 0.8V to 5.5V. The RUN/SS pin provides both soft-start and enable features. OPTI-LOOP compensation allows the transient response to be optimized over a wide range of output capacitance and ESR values. Current foldback limits MOSFET dissipation during short circuit conditions.
