Introduction to LTC3104EDE#TRPBF

The LTC3104EDE#TRPBF is a highly efficient, low voltage buck-boost regulator from Linear Technology. It works by proportionally controlling the supply of power from its two input terminals to its output terminal. The LTC3104EDE#TRPBF can provide a regulated voltage output to a wide range of loads for various applications.

Application Field

The LTC3104EDE#TRPBF is ideal for applications where the input voltage is lower than the output voltage. It is capable of providing a regulated output voltage from 0.6 V to 3.63 V with a current of up to 250 mA. It is well-suited for powering off-grid solutions such as solar-powered systems, where the input voltage varies between 0.5 V and 5 V.The LTC3104EDE#TRPBF is also an excellent choice for use in automotive, medical, industrial, and consumer applications, where reliable operation and extended battery life are key requirements. Its high efficiency, low noise, and low quiescent current make it a great choice for devices that operate off of battery power and need to extend battery life.

Working Principle

The LTC3104EDE#TRPBF operates on a buck-boost power conversion architecture. It is a synchronous boost converter that regulates an output voltage by proportionally controlling the power conveyed from its two input terminals to its output terminal.The input terminals of the buck-boost converter are connected to circuit elements that supply power to the device. These comprise a linear regulator (LDO) and a MOSFET switch. Depending on the load demand and input supply, the regulator functions as either a switch, a buck or a boost converter.When the LTC3104EDE#TRPBF operates as a buck converter, it connects the positive input terminal to the output terminal and, then, provides a regulated output voltage. When operated as a synchronous boost converter, it connects the lower input voltage to the output terminal. When it operates as a switch, it turns on and off to create high and low voltage levels to drive the output voltage.

Conclusion

The LTC3104EDE#TRPBF is a highly efficient, low voltage buck-boost regulator from Linear Technology. It is capable of providing a regulated output voltage from 0.6 V to 3.63 V with a current of up to 250 mA. It is ideal for applications where the input voltage is lower than the output voltage, such as off-grid solutions and automotive, medical, industrial, and consumer applications. It operates on a buck-boost power conversion architecture and proportionally controls the power conveyed between its two input terminals and its output terminal.
