Introduction

The AN80L36RMSTX is a voltage regulator that belongs to the class of Linear PMIC (Power Management IC) regulators. It is designed to work as a point-of-load applications and is able to provide single fixed-voltage regulation up to 3.6V when operating at up to 40V of input voltage. This voltage regulator comes with several safety features such as over-voltage and over-current protection, which makes it suitable for board-level applications in commercial, industrial, and automotive environments. Thanks to its internal power MOSFET and its low power loss, it can achieve an efficiency up to 94% when operated in the range of 1 to 6 A.

AN80L36RMSTX Application Field

The AN80L36RMSTX is suitable for multiple application fields, including the automotive, commercial, and industrial sectors. In automotive sector, it can be used in auxiliary systems requiring low-output and high-input voltage regulation. It can also be used in alternative energy and industrial applications, providing safe, reliable, and scalable power solutions where long-term reliability and efficiency are required. Because of its ability to provide highly accurate and reliable power supply, it is also suitable for high-precision industrial applications such as over-current and over-voltage protection circuits.

AN80L36RMSTX Working Principle

The AN80L36RMSTX voltage regulator operates on the principle of pulse-width modulation (PWM) to achieve energy efficiency and precise voltage regulation. It uses a duty-cycle control loop for precise voltage regulation by modulating the on-time of a MOSFET switch at a high frequency. In order to achieve precise and stable regulation, the regulator\'s PWM controller compares its adjustable output voltage set point with its actual output voltage. If the actual output voltage is higher than the set point, it shuts off the MOSFET switch to decrease the output voltage and vice versa.The AN80L36RMSTX voltage regulator also features over-voltage and over-current protection. It has an integrated voltage detector which monitors the input voltage and provides an over-voltage protection. It also integrates a power MOSFET with built-in temperature heatsink to protect against over-current conditions. The over-voltage and over-current protection features can be independently enabled/disabled via the control pins of the IC.

Conclusion

The AN80L36RMSTX is a voltage regulator that belongs to the class of Linear PMIC regulators. It is suitable for low-output and high-input voltage applications such as automotive, commercial, and industrial sectors. This regulator operates on the principle of PWM pulse-width modulation and it has built-in safety features such as over-voltage and over-current protections. Due to its low power loss and high efficiency, it is ideal for board-level applications in harsh industrial and automotive environments.
