LTC3897 - PolyPhase Synchronous Boost Controller

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.

Features

  • n Input Supply Range: 4.5V to 65V (Up to 75V Surge) n Reverse Input Protection to.
  • 40V n In-Rush Current Control, Overcurrent Protection and Output Disconnect for Boost Converter n Input Voltage Surge Protection with Adjustable Clamp Voltage n Onboard Ideal Diode Controller n Low Quiescent Current: 55µA n 2-Phase Operation Reduces Required Input and Output Capacitance and Noise n Output Voltage Up to 60V n Adjustable Gate Drive Level 5V to 10V (OPTI-DRIVE) for Logic-Level or Sta.
