It is part of the Power Management IC (PMIC) line of regulators and is intended for various applications, including automotive, industrial and consumer use. In this article, we will discuss the application field and working principle of the LM9076BMAX-5.0.

Application Field

The LM9076BMAX-5.0 is a universal regulator, providing precise voltage and current configuration to various systems. It has a wide operating range and can operate over temperature ranges of -40℃ to +125℃, allowing it to be used in extreme conditions, such as automotive and industrial applications. The device is suited for a variety of general purpose, continuous-load applications in both 12 and 24V automotive systems, such as AM/FM tuners, CD/DVD players and other infotainment equipment. It can be used to provide a stable and adjustable output in battery-powered systems, as well as in power conversion applications.

Working Principle

The LM9076BMAX-5.0 is an adjustable voltage regulator and the main principle applied for its operation is the voltage-regulating loop (VRL). The loop consists of a feedback circuit, an error amplifier and a bandgap reference. The error amplifier is used to compare the output voltage with a reference voltage and create an output voltage error signal. This signal is then fed to the feedback circuit, which adjusts the output voltage until the error signal is zero.The device also has two control pins, one to adjust the output voltage and one to adjust the current. The output voltage can be adjusted from 0.8V to 5.0V in 200mV steps, while the current can be adjusted from 0.1 to 1.3A in 0.1A steps. The LM9076BMAX-5.0 also features a precision bandgap reference, temperature coefficient and 20℃ temperature stability.

Conclusion

The LM9076BMAX-5.0 is a versatile voltage and current regulator from Texas Instruments which can be used in various automotive, industrial and consumer applications. It can provide precise adjustment of output voltage and current, as well as low temperature coefficient, 20℃ temperature stability and wide operating range. The main principle applied by the regulator is the voltage-regulating loop, which is composed of a feedback, error amplifier and bandgap reference. The device is an excellent choice for providing stable and adjustable output in battery-powered systems and power conversion applications.
