Working Principle of LT3014BMPS5#TRMPBF

The LT3014BMPS5#TRMPBF utilizes a synchronous buck topology to achieve adjustable output voltage regulation. This topology consists of two main components: - High-Side MOSFETs: The high side MOSFETs control the current flow between the input and the output of the device. When there is a voltage difference between the input and output terminals, the high side MOSFETs switch between conductive (on) and non-conductive (off) states. This switching of the MOSFETs controls the current flow between the input and output and the amount of power provided to the load.- Low-Side Switches: The low side switches complete the topology by connecting and disconnecting the output of the device from the ground. The low side switches also work in a similar fashion to the high side MOSFETs by switching between open (off) and closed (on) states.

Conclusion

The LT3014BMPS5#TRMPBF is a positive adjustable voltage regulator that can be used to step down a DC voltage from 3.2V to 40V and provide a precise, low voltage output.
