5 volts 3A Dc DC converter circuit design project using LTC3113 IC


Posted on Feb 5, 2014

Using the LTC3113 fixed frequency, buck-boost DC DC converter can be designed various power supplies circuits 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. Higher output current is

possible in step down (buck) mode. Integrated low RDS(ON) power MOSFETs and a programmable switching frequency up to 2MHz result in a compact solution footprint. Some features of the LTC3113 IC include <1 A shutdown current, integrated soft-start, short-circuit protection, current limit and thermal overload protection. The error amplifier output (VC) determines the output duty cycle of each switch. The low RDS(ON), low gate charge, synchronous power switches provide high frequency pulse width modulation control.
