Introduction to LTC3255EMSE#TRPBF

Linear Technology Corporation has developed a highly efficient, low quiescent current synchronous step down DC-DC converter known as the LTC3255EMSE#TRPBF. This DC-DC converter is configured by a fixed voltage feedback loop and is specifically designed for low power and medium power applications in both consumer and industrial electronic products.

Application Field of LTC3255EMSE#TRPBF

The LTC3255EMSE#TRPBF converter is typically used for applications where a low quiescent current is necessary and highly efficient performance is desired. It is ideal for portable devices, such as cellular phones, digital cameras, and personal digital assistants (PDAs). Its high switching frequency also allows for the use of low component count design, thus making its use applicable in cost-sensitive product designs. It can also be used in various industrial applications including audio and lighting systems, as well as HVAC equipment.

Working Principle

The LTC3255EMSE#TRPBF DC-DC converter operates by utilizing synchronous rectification to convert an input voltage to a desired output voltage. This is done by utilizing an internal power switch, driving a desired current through a low resistance current-sense resistor, and using this information to regulate the output voltage. The device is able to operate at a wide range of input voltages, from 4.5V to 30V, with an output current of up to 1.2A. By monitoring the voltage across the sense resistor and the voltage at the output, the converter can adjust the switch duty cycle to ensure an output voltage that is proportional to the desired load. In addition, switching frequency can be altered via an on-board resistor to allow greater design freedom.

Conclusion

The LTC3255EMSE#TRPBF DC-DC converter is a highly efficient and low quiescent current device that is well-suited for use in portable and low power designs where high efficiency is desired. The wide range of input voltages and adjustable switching frequency allows for greater design flexibility, making the LTC3255EMSE#TRPBF a useful device for various applications where the regulated voltage needs to be controlled.
