DC686A

DC686A is a demonstration circuit featuring the LTC3780, a high efficiency step-up/down DC/DC converter that can regulate its O/P from I/P voltages both above and below the O/P. This board delivers 12V at 5A from an input range of 5 to 32V. The LTC3780 is a high-performance buck-boost switching regulator controller designed O/p regulate O/Ps using I/P voltages above, below or equal to O/P voltage. The constant frequency current mode architecture allows phase-lockable frequency of up to 400KHz. A wide I/P and O/P range w/ continuous transfer function through all operation modes, makes product ideal for automotive, telecom and battery systems. The LTC3780 is equipped w/ fault protection provided by an O/P OV comparator and internal foldback current limiting. Soft-start control is accomplished w/ an external capacitor that controls the slew rate of reference voltage for error amplifier, which in turn controls output slew rate of regulator, and optional timed short-circuit shutdown.
