The S-85S1PD30-I8T1U works on the principle of pulse width modulation, or PWM. This works by modulating the pulse width out of the regulator by varying its frequency as well as its duty cycle. A fixed reference voltage is used, and the PWM signal is created by comparing the reference voltage with the voltage of the output, for which the regulator should be providing power. By modulating the pulse width, the output of the regulator is (relatively) continuously adjusted. This allows for a higher degree of accuracy and efficiency, compared to a linear voltage regulator.

The S-85S1PD30-I8T1U has multiple advantages over other types of voltage regulators. It has a wide input voltage range (up to 30V) and has a low quiescent current. It also has a low operating temperature, making it ideal for portable applications. Lastly, its wide range of control options make it highly customizable. This allows designers to tailor their applications to their specifications.

In summary, the S-85S1PD30-I8T1U is a highly efficient, compact, and integrated DC-DC switching regulator PMIC with an integrated low-loss FET. It works on the principle of pulse width modulation and offers many features, including thermal shutdown protection, overtemperature protection, overcurrent protection and wide input voltage range. The S-85S1PD30-I8T1U is ideal for use in automotive electronic systems, switched mode power supplies, medical equipment, display backlighting, portable communication systems, industrial control systems and motor control systems.
