TPS73630DBVT is a high voltage linear regulator. It is a three-terminal positive voltage regulator designed for systems operating from a single supply. This device provides the industry\'s highest supply current and high efficiency in a small SOT-23 package, allowing designers to deliver an optimized portable product.

Application Field of TPS73630DBVT

As a high voltage linear regulator, the TPS73630DBVT is mainly applied in voltage supervision circuits, LCD bias supplies, digital coder supplies, optical modules, set-top box and consumer electronics. Besides, it is suitable for portable communication devices powering the processor, dynamic random access memory (DRAM) and non-volatile memory (NVM). In summary, its application fields include consumer electronics, power management, digital appliances, and ports and mobile equipment.

Working Principle of TPS73630DBVT

The working principle of TPS73630DBVT is based on a conventional linear regulator with a voltage reference combined with an error amplifier. The output voltage of the TPS73630DBVT is determined by the external feedback resistors, R1 and R2. The error amplifier compares the output voltage with the regulated voltage and adjust the gate drive of an N-MOSFET. This MOSFET is placed in series with the output voltage. The purpose of the TPS73630DBVT is to maintain the output voltage constant even if there is a variation in the input voltage, as well as when there is a variation in current in the load. An internal thermal limiting circuit is also provided to protect the MOSFET against current overloads.

The TPS73630DBVT offers a variety of protection features to prevent short-circuiting, over-voltage and over-temperature conditions. These features include an adjustable maximum on-time (TMAX) with an internal timer that shuts down the device when the maximum on-time is exceeded. The device also includes an adjustable over-voltage lockout (OVLO) voltage, detected by an internal over-voltage comparator, which turns the P-MOSFET off when the set voltage is exceeded.

In addition, the TPS73630DBVT has an excellent line transient response and low output noise. These features enable very quality power supply designs. In simple words, the TPS73630DBVT is a high voltage linear regulator with great specifications that offer excellent performance and reliability.

Conclusion

In conclusion, the TPS73630DBVT is a suitable solution for portable applications in the consumer, industrial and even military fields. It provides the best noise performance, most efficient power transfer, and highest load current in a small, low-cost package. By taking all the features of the device under consideration, designers will be able to create high quality products with reliable performance and long lifetime.
