The working principle of the LM2597HVMX-12/NOPB is based on the slowing of an inductor’s electromagnetic field. In a buck converter, energy is transferred from the input to the output by switching a transistor on and off. When the switch is turned on, energy is stored in magnetic fields in the inductor; when the switch is turned off, energy is released and transferred to the output. The LM2597HVMX-12/NOPB works by using a constant current line regulated switching converter to provide a regulated output voltage.

In summary, the LM2597HVMX-12/NOPB is a highly-integrated synchronous step-down converter from Texas Instruments. The device is capable of providing an adjustable output voltage from 1.235 volts to 28 volts with ±2% accuracy and can be used in a wide range of power supply and conversion applications. The LM2597HVMX-12/NOPB also has numerous protection features and is rated for up to 4 A of continuous current efficiency of up to 97%.
