LTC3716 - 2-Phase, 5-Bit VID, Current Mode, High Efficiency, Synchronous Step-Down Switching Regulator
An operating mode select pin (FCB) can be used to regulate a secondary winding or select among three modes including BurstModeTM operation for highest efficiency. Aninternal differential amplifier provides true remote sensing of the regulated supply’s positive and negative output terminals as required in high current applications.
The RUN/SS pin provides soft-start and optional timed, short-circuit shutdown. Current foldback limits MOSFET dissipation during short-circuit conditions when the overcurrent latchoff is disabled. OPTI-LOOP compensation allows the transient response to be optimized for a wide range of output capacitors and ESR values.
