TPS77615PWPR

TPS77615PWPR Application Field and Working Principle

The TPS77615PWPR is an integrated voltage regulator, with internal low on resistance, low dropout voltage and low quiescent current. It features an internal P-channel MOSFET, eliminating the need for an external P-channel MOSFET in DC/DC converter applications. The device is designed to provide a regulated output voltage, with UVLO and over current protection, as well as output voltage tracking, making it suitable for a variety of power supply solutions.

TPS77615PWPR Application Field

This integrated linear regulator is ideal for applications that require a stable, low noise and low current consumption power supply, such as battery powered devices. It can also be used in topology converters, where it provides a low ESR and fast transient response due to its low output impedance. Other applications include industrial, automotive and wireless power solutions.

TPS77615PWPR Working Principle

The TPS77615PWPR integrated voltage regulator works in a similar way to traditional linear voltage regulators, with the addition of internal protection features and the integrated P-channel MOSFET which eliminates the need for an external P-channel MOSFET for the converter topology. Its operation is based on a voltage reference, which is compared to its feedback voltage. The error current created will flow through the pass element (in this case a P-channel MOSFET). The pass element creates an output voltage, which is compared to the reference voltage to ensure it remains stable.

The device also features various protection features, such as over current protection, which limits the output current; undervoltage lockout, which stops the device from turning on when the input voltage is too low; and over temperature protection, which turns off the device in the event of overheating.

Conclusion

The TPS77615PWPR is a high performance and low quiescent current integrated voltage regulator, ideal for a variety of power supply solutions. It features an integrated P-channel MOSFET, providing improved transient response and low ESR as well as a number of features for improved protection. This makes it suitable for battery-powered and other applications which require stable and noise-free power.
