The device supports adjustable overcurrent threshold and overvoltage protection, making it suitable for high-power applications.

Working Principle

The TPS55165QPWPRQ1 is a DC-DC switching regulator that converts the input voltage to a fixed output voltage. The device is capable of regulating input currents of up to 5.5A. The device works by rapidly switching the input voltage to a specific frequency. Initially, the voltage is switched by a power MOSFET. This switch is then passed through an inductor, where the voltage is increased, and through a capacitor, where it is stepped down to a fixed output voltage. The output voltage is then regulated by a voltage regulation circuit, which maintains the output voltage despite input voltage variations.

Applications

The TPS55165QPWPRQ1 is suitable for a wide range of applications such as automotive, computing, industrial, networking, and telecommunications. Its wide input voltage range and adjustable output voltage makes it useful for a variety of applications. For example, it can be used as a power supply in a car, as a power source for a computer, or as an adjustable voltage regulator in industrial applications. For networking and telecommunications applications, the device can be used to provide a surge protection for power supplies, which is necessary when working with active and static electrical components.
