Working Principles

The NX5P2090UKZ is a step-down (buck) converter that efficiently converts a higher input voltage to a lower output voltage. It utilizes a switching regulator topology, which allows for high efficiency by minimizing power dissipation. The integrated control circuitry adjusts the duty cycle of the internal switch to regulate the output voltage according to the feedback signal.

During operation, the input voltage is applied to the VIN pin, and the internal switch rapidly turns on and off to control the energy transfer from the input to the output. This switching action reduces the voltage across the pass element, resulting in minimized power loss. The regulated output voltage is available at the VOUT pin.
