TPS65276VDAPR is a Voltage Regulators device developed by Texas Instruments. It's designed for DC/DC voltage regulator applications, especially in applications when high current is needed and space is limited. The device utilizes two independent synchronous buck regulator outputs and two linear regulator outputs. It is particularly suitable for processor core voltage regulation demanding applications like industrial and medical systems.

TPS65276VDAPR device is a highly integrated Switching Regulator device suitable for applications demanding high current regulation with its integrated 95A/100 MHz MOSFETs and an ultra-low quiescent current. It is stable with a minimum number of additional external components like input/output capacitors and inductor. The device regulates two independent but identical outputs, each output is capable of providing up to 12V at 6A, and it has a user-adjustable buck converter output of 1.5V to 10V. With its wide input operating voltage range of 4.5V to 28V, the device is suitable for 3.3V, 5.0V, 12V or automotive applications. It also features an adjustable output linear regulator output of 1.2V, 1.8V and 2.8V. In addition, it has over-temperature protection, short-to-ground and short-to-battery protection. All these features gives it a wide range of applications for industrial and medical systems.

The working principle of the TPS65276VDAPR device is based on its state-of-the-art voltage regulation technology. An oscillator is used to generate a pulse width modulation (PWM) signal and the converter is controlled with a fixed duty cycle PWM technique. The internal MOSFETs provide power to the converter and they are driven by the built-in gate drivers. The gate drivers actively regulate the switching speed and duty cycle of the MOSFETs to reach the voltage regulation requirement. The device is also equipped with an adjustable voltage loop feedback, which helps to achieve a more precise voltage regulation.

The device's 95A/100 MHz MOSFETs and an ultra-low quiescent current ensures that it can deliver up to 6A. In addition, its remote sense capability eliminates the need for long cables and it also has built-in soft-start and hiccup-mode short-circuit protection. These features makes the device extremely suitable for processor core voltage regulation demanding applications like industrial and medical systems.

In conclusion, the TPS65276VDAPR device from Texas Instruments is a reliable, efficient and cost-effective way to address voltage regulator applications. Its wide input operating voltage range, 95A/100 MHz MOSFETs and an ultra-low quiescent current makes it an ideal solution for high current regulation in applications that requires space limitations. The device can be used in industrial, medical and automotive systems, making it a versatile and cost-effective solution for many applications.
