It is available in a 5-pin TSOT package and provides a regulated output voltage at a wide range of currents. It is designed to convert a regulated input voltage to a regulated output voltage up to 1.2A and operate over an input voltage range of 2.5V to 5.5V. The LT3480EMSE#PBF features a wide range of features, including instantaneous power control, easy to use interface, adjustable switching frequency and low noise operation.

Application Field
The LT3480EMSE#PBF has potential applications in a variety of different scenarios. With its wide range of features, it is suitable for use in portable power supplies and other applications that require high current and precise control in a limited space. It can be used in the basic battery-regulated circuit to ensure that the proper power is being supplied to the peripheral components. Additionally, the LT3480EMSE#PBF is suitable for use in automotive engine management systems, where it can reduce the noise generated by the system.

Working Principle
The LT3480EMSE#PBF operates according to a pulse width modulation (PWM) switching scheme. In this scheme, the switch is repeatedly switched on and off at a pre-determined rate (known as a frequency). The frequency is determined by the user via the resistor divider connected to the Switch Frequency Control pin. During the period of the switch being on, the attached inductor will store a certain amount of energy, which is then discharged during the period of the switch being off. In this manner, the input voltage can be “chopped” into a series of rectangular pulses, which can be filtered and regulated to provide a stable and accurate output voltage. Furthermore, by altering the pulse width (i.e., the time period of the switch being on), the output voltage can be precisely controlled.

Conclusion
The LT3480EMSE#PBF is a highly versatile DC/DC switching regulator, suitable for a variety of applications. It offers a wide range of features, including output voltage up to 1.2A and adjustable switching frequency. By using a PWM switching scheme, the LT3480EMSE#PBF can precisely control the output voltage, which makes it suitable for use in automotive engine management systems as well as in other high-power applications. With its high performance and low noise characteristics, the LT3480EMSE#PBF provides a reliable and attractive solution for a variety of applications.
