The LTC3897 is a synchronous boost DC/DC controller with surge stopper and ideal diode controller.The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor?requirements, allowing the use of smaller inductors than the single-phase equivalent.

The integrated ideal diode controller drives another N-channel MOSFET to replace a Schottky diode for reverse input protection and voltage holdup or peak detection. It controls the forward voltage drop across the MOSFET and minimizes reverse current flow.The LTC3897 is available in thermally-enhanced 38-pin leadless QFN or 38-lead TSSOP packages.Applications Industrial Automotive Military/Avionics

The LTC4079 is a low quiescent current, high voltage linear charger for most battery chemistry types including Li-Ion/Polymer, LiFePO4, Lead-Acid or NiMH battery stacks up to 60V.
