Working Principle of LM53625LQRNLTQ1:

The operation of the LM53625LQRNLTQ1 is based on the buck converter topology. The input voltage is stepped down by a switch, coupled with an inductor, which is driven by an internal oscillator operating at a frequency of 1.1MHz. The output voltage is configured through a single resistor and limited to a maximum of 6V. The power switch, driven by the inductor current, is consumed to minimize power losses and minimize output voltage ripples. The internal short-circuit protection protects against overloads and short circuits.

Applications Areas:

The LM53625LQRNLTQ1 is suitable for a vast array of low noise voltage applications in the following sectors: professional and commercial audio, telecommunications, computing, networking, gaming, biomedical, instrumentation, medical imaging, automotive, industrial motors and many more. Its superior efficiency, low noise, and adjustable output voltage makes it an ideal choice for these kinds of applications.
