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.

Other features include <1μA shutdown current, integrated soft-start, short-circuit protection, current limit and thermal overload protection. The LTC3113 is housed in the thermally enhanced 16-lead (4mm × 5mm × 0.75mm) DFN and 20-lead TSSOP packages.

Product Detail

Demonstration Circuit 1551A is a wide Vin range, highly efficient, fixed frequency buck-boost converter. The unique 4-switch, single inductor architecture provides low noise and seamless operation from input voltages above, below, or equal to the output voltage. The LTC3113 features selectable PWM or Burst Mode operation and an oscillator with a programmable frequency from 300kHz to 2MHz. The LTC3113 can deliver up to 3A of continuous output current to satisfy most demanding applications. Higher output currents are possible in step-down (buck) mode. The LTC3113 operates with a 1.8V to 5.5V input and output voltage range. The demonstration board has been designed to operate over the full input voltage range, with VOUT set to 3.3V and IOUT of 3.0A. For VIN < 3V, IOUT capability is reduced.

Tools & Simulations 1

LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.
