Introduction to PMIC – Supervisors

A Power Management Integration Circuit (PMIC) is an integrated circuit comprised of dedicated ICs and peripheral circuits responsible for the oversight and control of the power supply of an electronic system. PMICs are used in devices ranging from mobile phones to laptop computers, and serve to monitor and regulate the efficiency and power consumption of the device they are installed in. Under PMICs are supervisors, which are specialized ICs designed to regulate and manage the power output of the device, as well as perform other power related functions. Supervisors place special emphasis on protecting the energy that is supplied to the device, as a result of which the efficiency and longevity of the device are optimized.

X5163S8-2.7AT1 Application Field and Working Principle The X5163S8-2.7AT1 is a supervised Low Drop Out (LDO) linear regulator intended for power management applications requiring minimum standby current drain and accuracy. This means that it is ideally suited for use in applications such as computers, mobile phones and other portable electronic devices, since it greatly reduces the power consumption in an idle state and offers excellent load regulation. Furthermore, the X5163S8 series provides a wide range of output voltage and current, so they can be used in a variety of applications. The X5163S8-2.7AT1 works with a wide input voltage range of 2.8V to 6V and offers adjustable output voltage with ±1% accuracy. It is also capable of supplying output current up to 150mA, making it well suited for applications requiring higher load current. The X5163S8-2.7AT1 also comes with other features such as current limit, over-voltage protection, over-temperature protection, and short-circuit protection. The working principle of the X5163S8-2.7AT1 can be summarized in 3 steps:

• Step1: The device will first measure the input voltage to the IC and compare it with the desired output voltage. If the input voltage is within the specified range, then the desired output voltage is set.
• Step2: The IC will then adjust the output voltage using its adjustable output capability, allowing it to reach the desired output voltage.
• Step3: The IC will then regulate the current and power supplied to the device, as well as provide various protection features for the device.

The X5163S8-2.7AT1 is extremely power efficient and can minimize standby current drain for applications consuming very low power when the main supply is off. Furthermore, the device is also capable of having excellent load regulation over the entire input voltage range, which makes it perfect for applications requiring high accuracy over a wide input voltage range.

Conclusion

In conclusion, the X5163S8 series Low Drop Out (LDO) linear regulator is an excellent solution for applications requiring minimum standby current drain and accuracy. Its wide input voltage range and adjustable output voltage capability make it suitable for a wide range of power management applications. Furthermore, its current limit, over-voltage protection, over-temperature protection, and short-circuit protection make it a great choice for applications that require protection from power related issues.
