Linear introduces the LTC3897, a multiphase synchronous boost DC/DC controller with an input surge suppressor and an 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 inductors that are smaller than comparable single-phase solutions.
