Introduction to BU1BTD2WNVX-TL PMIC - Voltage Regulators - Linear

The BU1BTD2WNVX-TL PMIC (Power Management Integrated Circuit) - Voltage Regulators - Linear is a dual output step-down converter designed to provide a variable output from 0.8V up to 5.5V. It offers a wide input range of up to 25V and 5A total output current. With its integrated intelligence, this component provides adjustable current limit, fault protection, and thermal shutdown, while maintaining a high efficiency of up to 85%.

Application Field

BU1BTD2WNVX-TL PMIC - Voltage Regulators - Linear can be utilized in various applications such as powering Digital Video recorders (DVRs), supplying power to processors and graphics cards, and low power systems. It can also be used as a system power supply source for backup power support and voltage boosting/stabilizing applications.

Working Principle

BU1BTD2WNVX-TL PMIC - Voltage Regulators - Linear works on the principle of linear voltage regulation. The component is incorporated with a low quiescent current design, automatic skip mode technology and an efficient synchronous rectification, allowing it to operate briefly in a burst mode during light load conditions. The component features a voltage feedback loop to maintain an output voltage that is adjustable via external resistors. The voltage regulation is achieved by reducing or increasing the switching frequency, as the output voltage approaches its target. As a result, it produces a steady DC voltage, regardless of load conditions. The component also operates with a built-in current limit feature which limits the total output current to 5A. The current limit is user adjustable whereas the maximum output current is a function of the input voltage. In case of a sudden load increase, the component senses the increase in current and initiates its skip mode operation, limiting the maximum output current. Additionally, it features an internal thermal shutdown for over temperature protection and a short circuit protection.

Conclusion

The BU1BTD2WNVX-TL PMIC - Voltage Regulators - Linear is a highly versatile and reliable dual-output step-down converter that can be used in a variety of applications. Its low quiescent current design, adjustable current limit, fault protection and thermal shutdown ensure that the component operates efficiently, even during heavy load conditions. Therefore, it is an excellent choice for powering digital video recorders, system power supply source and other low-power applications.
