It takes an input voltage of up to 27V and transforms it into a regulated output voltage. This is accomplished by controlling the amplitude of voltage through a voltage divider circuit. This circuit is made up of resistors and an integrated MOSFET. The MOSFET acts as an electronic switch and is controlled by a current that is generated by an external control circuit. Whenever the current reaches a predetermined limit, the MOSFET turns on and reduces the voltage. When the voltage falls below the predetermined level, the MOSFET turns off and increases the voltage, thus regulating the output voltage.The S-812C25AUA-C2FT2G voltage regulator is ideal for use in low cost, non-isolated applications requiring fast transient response, low power dissipation, and tight output voltage regulation. Due to its built-in protection features, the S-812C25AUA-C2FT2G can be safely used in applications such as power adapter, notebook and other DC/DC applications. Its wide input and output voltage range, integrated MOSFET, and adjustable temperature controlled current limit provide excellent power performance and reliable operation.
