LTC3897 PolyPhase™ Synchronous Boost Controllers

Analog Devices LTC3897 PolyPhase™ Synchronous Boost Controllers with surge stopper provide input/output protection and an ideal diode controller. The device has a boost controller that drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements. This allows the use of smaller inductors than the single-phase equivalent. Synchronous rectification reduces power loss and eases thermal requirements.
