LT3680IMSE#TRPBF DC DC Switching Regulators Application Field and Working Principle

PMIC (Power Management Integrated Circuit) Voltage Regulators provides efficient and reliable power management solutions to wide range of end products. In recent years, DC-DC switching regulators are widely adopted and currently replacing earlier Linear counterparts for their high efficiency ratings and bread down output standard. The LT3680IMSE#TRPBF is a regime of isolated DC-DC switching regulators that has gained immense popularity due to its compact design and versatile feature set.The LT3680IMSE#TRPBF single package solution contains all the features required by an isolated DC-DC switching regulator in just 9mm x 11mm x 5.5 mm, making it incredibly versatile and ideal for a variety of applications and requirements.

Key Features of LT3680IMSE#TRPBF

The LT3680IMSE#TRPBF measures three key features, namely - efficiency, small size, and isolated output and it offers some of the best-in-class performance in all these three aspects. Efficiency Ratings: LT3680IMSE#TRPBF offers an impressive 92.4% peak efficiency rating, and a conversion usage as low as 0.4 mA per watt. It does so by using an advanced pulse width modulation (PWM) control technique combined with low Rds(on) MOSFETs integrated within the package that minimizes power losses in the conversion cycle.Ultra-Small Package Size: The LT3680IMSE#TRPBF offers all the features of a conventional DC-DC switching regulator in a fraction of the size in 9mm x 11mm x 5.5 mm, making it ideal for applications where space is a premium. Flexible Input and Isolated Output: The LT3680IMSE#TRPBF, by default operates from an input voltage range of 2.25 V to 25.0V, with an extended input voltage range of up to 40 V with proper configuration, making it ideal for a wide range of applications. Apart from that, it offers an isolated output of up to 36V, coupled with a fast transient response that makes it suitable for a range of widespread performance.

Design and Working Principle

The LT3680IMSE#TRPBF, fused with high functioning features offers the best performance in terms of efficiency, size and isolated output among similar solutions available in the market and is suitable for a range of requirements. The LT3680IMSE#TRPBF design consists of a synchronous buck controller and two sets of power MOSFETs in the front and in the rear. The input voltage is rectified before being fed to the internal high-side power MOSFET, where it is ultimately buck regulated to the desired voltage level based on the requirements. The power inductor then filters the converted voltage, before it is passed through an opto-coupler for isolation, and then delivered to the output load.

Advantages of using LT3680IMSE#TRPBF

LT3680IMSE#TRPBF has become the regulator of choice among numerous system designers for its efficient performance, small size and isolated output capability at an increased voltage of 36 V, making it an ideal solution for numerous applications that require increased output power levels , such as industrial automation, test equipment, distributed power supplies and many more.
