The device’s working principle is based on a Buck converter topology, which allows for efficient conversion of an input voltage to any desired output voltage. A Buck converter is a DC-DC switching regulator that operates by converting a higher input voltage to a lower output voltage through a process of energy transfer from the input to the output. This process is achieved by a switching element, which is usually a transistor or a MOSFET, which is switched on and off at high frequency. When the switch is turned on, the input voltage is applied across a series of inductors, which causes current to flow through the circuit. When the switch is turned off, this current is then used to create a magnetic field, which in turn is used to create the required output voltage.

In summary, the S-85S1PC19-I8T1U is a DC-DC switching regulator manufactured by Shenzhen S-Union Technology Co., Ltd., and is part of their range of PMICs. This device is suitable for a wide range of industrial and automotive applications and provides an adjustable output voltage range of 0.8V to 28V.
