Additionally, the integrated overvoltage protection and power-on reset make it ideal for use in battery-powered systems.

Working Principle

The TPS75415QPWPG4 is a linear voltage regulator, which works by using a voltage reference, typically a Zener diode, and a series of transistors to control the output voltage of the device.The internal transistors are switched on and off at high speeds to ensure that the output voltage is as close as possible to the reference voltage set by the Zener diode. This is done by a closed loop control system, which compares the reference voltage with the actual output voltage of the device. Depending on the difference between these two, the number of transistors that are switched on and off is adjusted accordingly, to maintain the desired output voltage.

Conclusion

The TPS75415QPWPG4 is a high efficiency and low quiescent current linear voltage regulator (LVR). This PMIC offers a wide operational range, adjustable output voltage, and adjustable output current, making it suitable for a variety of applications, including digital consumer electronic products, embedded systems, and battery-powered systems. Additionally, the integrated overvoltage protection and power-on reset make it ideal for use in battery-powered systems. The device works by using an internal voltage reference and a series of transistors to control the output voltage, with a closed loop control system to make sure the output voltage is as close as possible to the reference.
