The S-1112B54PI-L7NTFU is an example of a linear voltage regulator and, therefore, is classed as a PMIC – Voltage Regulator - Linear (PMIC stands for Power Management Integrated Circuit, and is a sub-category of integrated circuits).

Linear voltage regulators are used to provide steady and stable power supply to electronic circuits. They are used to reduce the noise of the power supply signal and provide a steady current for more delicate applications. A linear voltage regulator can also be used to convert a high-voltage input to a lower-voltage output, and this is the basic ability of the S-1112B54PI-L7NTFU.

The S-1112B54PI-L7NTFU is a 5V output, 15V to 30V input voltage regulator with a maximum 3A output current with a 100kHz fixed switching frequency. It is a single-channel, low-side buck converter, meaning it has a fixed output voltage of 5V regardless of the input voltage or load current fluctuation. It is also equipped with short-circuit protection, thermal shutdown, voltage feedback, and a power-good indicator, making it a reliable and well-suited voltage regulator for various designs.

Application field

The S-1112B54PI-L7NTFU is ideal for applications that require a constant and stable power supply, especially for more delicate circuits. It can be used as a power supply for laptops, phones, cameras and other portable electronic devices. It can also be used for power conversion for a wide range of industrial and consumer applications. Examples include medical equipment, communication systems and consumer audio/visual products.

Working Principle

The S-1112B54PI-L7NTFU operates using a linear voltage regulator circuit. In this type of circuit, the voltage input is capacitively coupled to the output via an inductor and a switching transistor. When the input voltage is higher than the output voltage, the switch transistor turns on and the inductor stores energy. When the input voltage is lower than the output voltage, the switch transistor turns off and this stored energy is released, supplying the output node with the required voltage.

The S-1112B54PI-L7NTFU is also equipped with other key protection features, such as short-circuit protection and thermal shutdown, so the device can be safely operated in the rated conditions. These features are designed to protect the device from over-current, exceeding its rated power dissipation and thermal runaway.

In summary, the S-1112B54PI-L7NTFU is an advanced linear voltage regulator designed for power conversion applications, and it is primarily ideal for offering a constant and stable power supply to delicate devices, such as laptops, phones, cameras and other portable electronics, as well as various industrial and consumer applications including medical equipment, communication systems and consumer audio/visual products.
