Introduction for TPS79915QDRVRQ1

TPS79915QDRVRQ1 is a Linear Voltage Regulator designed specifically for powering devices with high current requirements, such as FPGAs, powerful digital communication systems, sensors, and other digital interfaces. It is a buck-boost type voltage regulator, which features an adjustable output voltage range from 0.8 eV to 4.25 V, while providing current up to 10A.The module has several built-in safety features, such as over-temperature protection, current limiting, and short circuit protection. This ensures that the regulated output voltage always remains within a safe range and helps protect the device or system from damage due to fault currents or thermal runaway. Furthermore, the TPS79915QDRVRQ1 features an integrated soft start functionality to reduce inrush current and allow a smooth startup of the device. This combined with its wide input voltage range from 2.5 V to 8 V makes it suitable for a variety of applications.

Application Field of TPS79915QDRVRQ1 in Detail

TPS79915QDRVRQ1 is primarily used for providing high current supplies to devices with varying current requirements such as digital communication systems, FPGAs, displays, sensors and many other high-end devices. It is highly preferred in applications where high accuracy of output voltage and current are paramount, such as in test instruments, scientific instruments and medical devices.The integrated over-voltage, current limit and short-circuit protection, along with its low dropout operation ensures that the device will automatically shutdown upon occurrence of any fault condition and thus provide extra safety to the device. Furthermore, the device can also be used for controlling the current supply to a battery, providing extra protection against over-discharge of the cell. The device can also be used for power backup applications and the ability to have adjustable output current during master-slave transition further makes it suitable for powering up multiple rail systems. Furthermore, its high power efficiency and fast response time reduces the power consumption of the device and helps in achieving low standby power.

Working Principle of TPS79915QDRVRQ1

The function of the TPS79915QDRVRQ1 is to maintain a stable output voltage, regardless of varying input voltages or load conditions. This is done by a combination of a DC-DC converter and a Linear Voltage Regulator (LVR).The DC-DC converter provides step-down or step-up operation, depending on the input and output voltage requirements. It is the primary source of voltage regulation and it provides power to the output stage by converting the input voltage to the required output voltage.The LVR is used for fine voltage regulation. It is essentially a combination of a power amplifier, a voltage regulator, and an amplifier control circuit. Its output voltage is determined by the voltage drop across a differential amplifier, with an inverting input stage, a transistor-based output stage, and a feedback network.The combination of the DC-DC converter and the LVR helps in maintaining the stable output voltage of the device, even in the presence of large transient loads or varying input voltages.

Conclusion

TPS79915QDRVRQ1 is a high-performance, buck-boost type, adjustable output voltage regulator, specifically designed for providing high current supplies to digital communication systems, FPGAs, displays and various other high end devices. It features integrated over-voltage, current limit, and short-circuit protection, and is suitable for a wide input voltage range of 2.5 V to 8 V. Furthermore, its soft start functionality, high power efficiency and fast response time make it an ideal solution for many different applications.
