The S-812C41AMC-C2VT2U PMIC (Power Management IC) Voltage Regulator is a Linear type device that operates at a wide input voltage range between 8V DC and 200V DC. It provides an adjustable output voltage of up to 12V DC with an accuracy of ±1.5%, and current limits of up to 1.2A. This product is designed to meet the demands of industrial, automotive, and medical applications, making it a versatile voltage regulator.

The S-812C41AMC-C2VT2U is designed to achieve a high-efficiency power conversion with minimal ripples and noise. It has been designed with integrated high- and low-side Mosfets, a high-frequency bipolar constant-frequency current-mode, dual-mode error amplifier, and a voltage-feedback cascode amplifier. It also includes protection features such as under-voltage lockout, short-circuit protection, thermal protection and over-voltage protection. Furthermore, this product also has an internal thermal shutdown and overtemperature alarm, as well as an adjustable current limit.

The working principle of the S-812C41AMC-C2VT2U PMIC Voltage Regulator can be summarized as follows. In normal operation, the input voltage passes through the high- and low-side Mosfets and is then regulated by the voltage-feedback cascode amplifier to the preset output voltage. At the same time, a current limit circuit is activated to limit the output current at a level that is adjustable by the user. The voltage-feedback cascode amplifier then continuously adjusts the output level and eliminates any ripples caused by higher-frequency input current noise.

Once the output level is determined, the dual-mode error amplifier actively monitors the output voltage and keeps it at the desired level. The output voltage is compares with a reference voltage from an internal voltage-reference block, and the difference between this reference voltage and the output voltage is used to control the conduction and switching of the high- and low-side Mosfets. The high-frequency bipolar constant-frequency current-mode amplifiers are used to drive the high- and low-side Mosfets and maintain the output voltage at the preset level.

The S-812C41AMC-C2VT2U PMIC Voltage Regulator can be used in a variety of applications, such as industrial equipment, consumer electronics, communications equipment and HVAC systems. It also provides a number of features, including adjustable output voltage, current limit, under-voltage lockout, short-circuit protection, thermal protection and over-voltage protection. Furthermore, it is flexible and can be easily configured for various applications. The S-812C41AMC-C2VT2U PMIC Voltage Regulator is a versatile device, making it a great choice for all applications requiring a reliable and precise voltage regulator.
