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.
