Overview

Product Details

Pulsed Load or Portable RF Power Amplifier Application

The LTC3113 is a wide VIN range, highly efficient, fixed frequency, buck-boost DC/DC converter that operates from input voltages above, below or equal to the output voltage. The topology incorporated in the IC provides low noise operation, making it well suited for RF and precision measurement applications.

The LTC3113 can deliver up to 3A of continuous output current to satisfy the most demanding applications. Higher output current is possible in stepdown (buck) mode. Integrated low RDS(ON) power MOSFETs and a programmable switching frequency up to 2MHz result in a compact solution footprint. Selectable Burst Mode operation improves efficiency at light loads.
