Product details

Description

The LTC®3897 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.
