Working Principles

The MAX17502FATB+T is a voltage regulator that converts a higher input voltage to a lower output voltage. It utilizes a synchronous buck topology, where power MOSFETs are used to efficiently step down the input voltage. The integrated control circuitry ensures stable and regulated output voltage.

When enabled, the regulator actively controls the duty cycle of the power MOSFETs to maintain the desired output voltage. Feedback from the FB pin is compared to a reference voltage, and any deviation is corrected by adjusting the duty cycle. This closed-loop control mechanism ensures accurate regulation.
