Working Principles

The LM26001MXAX is a step-down (buck) voltage regulator that converts a higher input voltage to a lower output voltage. It utilizes a high-frequency switching technique to efficiently regulate the output voltage. The device operates by controlling the duty cycle of an internal power switch, which controls the energy transfer from the input to the output. This allows for efficient power conversion with minimal power loss.
