Working Principles

The MAX16126TCD/V+T is a synchronous buck regulator that converts a higher input voltage to a lower output voltage. It utilizes high-side and low-side MOSFETs to efficiently regulate the output voltage. The feedback pin (FB) allows the user to set the desired output voltage by connecting external resistors. The enable pin (EN) controls the on/off state of the regulator.

During operation, the regulator continuously switches the high-side and low-side MOSFETs to control the energy flow from the input to the output. This switching action, along with the inductor and capacitors, helps maintain a stable output voltage. The soft-start feature ensures a controlled startup, preventing excessive inrush current.

The MAX16126TCD/V+T also incorporates various protection features such as overcurrent protection, thermal shutdown, and under-voltage lockout (UVLO). These safeguards help protect the regulator and the connected circuitry from damage during fault conditions.
