Introduction
PMIC (power-management integrated circuits) are integrated circuits (ICs) for voltage regulation employed in a wide range of electronic systems, from personal electronics to industrial machinery. Specifically, the S-1333B16-A4T1U3 is a linear voltage regulator (LVR) device providing an adjustable output voltage and current limit, combined with overvoltage and current limit protections. This article provides an overview of the application field and working principle of the S-1333B16-A4T1U3.
Application Field
The S-1333B16-A4T1U3 is best suited for applications requiring a tightly regulated power source with effective overvoltage and current limit protections. This makes it a great choice for battery-powered applications, as well as embedded systems that require a stable power source. Additionally, its low operating current consumption and low temperature coefficient are ideal for applications where power conservation is of utmost importance.
Working Principle
The S-1333B16-A4T1U3 is a simplified switched-mode DC/DC converter, composed of a voltage regulator and an LC filter network. It provides a regulated output voltage through an adjustable resistor divider and an amplifier. When the supply voltage is lower than the desired output voltage that is set by this divider, the voltage regulator provides the necessary current. When the supply voltage is higher, the amplifier senses the difference and turns off the regulator. Thus, the output voltage is continuously maintained.
The S-1333B16-A4T1U3 is also equipped with an overvoltage protection circuitry to ensure the regulator is safely powered. This protection circuitry is composed of an overvoltage protection switch and an upper voltage limit comparator. Once the input voltage exceeds the upper limit, the overvoltage protection switch turns off the regulator.
Conclusion
In conclusion, the S-1333B16-A4T1U3 is a versatile linear voltage regulator device ideal for battery-powered and embedded applications requiring a tightly regulated power source with effective overvoltage and current limit protections. Its working principle involves a voltage regulator, an amplifier, and an overvoltage protection switch and comparator for safety.
