SG7915AK-DESC Application Field and Working Principle

SG7915AK-DESC is a voltage regulator that belongs to the linear category of PMIC (Power Management IC) products. It is designed for applications where the input voltage lies between the minimum voltage of 5.5V and the maximum voltage of 46V. It consists of current and temperature monitors as well as a linear regulator. The linear regulator is powered by a floating power supply which can be either internally or externally powered. It offers a continuous output voltage of 1.5V and a current up to 3A. The main application field of SG7915AK-DESC includes automotive, industrial and computing applications.

Working Principle

The SG7915AK-DESC voltage regulator operates on the principle of linear regulation. In this type of regulation, the output of the regulator is modulated to a fixed value by controlling the voltage across a control element. It is also a feedback type of control mechanism. A feedback voltage from the output is fed to the reference or control input. The control input compares the difference between the input and output of the regulator, and adjusts the output accordingly. It has two internal components, a control amplifier and the power transistor. In conventional linear regulators, the control amplifier is usually comprised of a voltage comparator and a current source, where the voltage comparator compares the voltage at the input of the regulator to the reference voltage and produces an error signal. The power transistor then adjusts the output voltage according to the error signal.

Advantages

The main advantage of the SG7915AK-DESC linear regulator lies in its ability to maintain a constant output voltage while keeping a low power dissipation. It also offers a wide input voltage range of 5.5V to 46V, further enhancing its extended utility. The wide input voltage range and low power consumption make it ideal for automotive and industrial applications. Its power transistor is also designed to have minimum distortion at the output, providing a stable and accurate voltage.
