TPS61040DBVR Typical application Circuitry

The TPS61040DBVR is a boost converter from Texas Instruments. Boost converters, as their name suggests, step up or "boost" an input voltage to a higher, regulated output voltage. Below is a detailed description of the TPS61040DBVR's features and functionalities:

1. Boost Converter: The TPS61040DBVR is specifically designed to step up a lower input voltage to produce a higher, regulated output voltage.

2. Input Voltage Range: The TPS61040DBVR operates over an input voltage range typically from around 1.8V to 6V.

3. Output Voltage: The device is capable of producing an output voltage that can go up to 28V, which makes it especially useful for applications that require a higher voltage rail. The actual output voltage is set based on the feedback through an external resistor divider network.

4. Switching Frequency: The TPS61040DBVR operates at a switching frequency of 1.2 MHz. This higher switching frequency allows for the use of smaller external components, particularly inductors and capacitors, which can save board space and reduce costs.

5. Packaging: "DBVR" in the part number indicates the device comes in an SOT-23 package, a small and compact package ideal for space-constrained applications.

6. Current Limit: The device has an internal current limit, providing protection against potential overcurrent conditions.

7. Protection Features: The TPS61040DBVR incorporates built-in protection mechanisms like thermal shutdown and under-voltage lockout. These features ensure the safe operation of the device under various conditions.

8. Control Modes: The device operates in pulse width modulation (PWM) mode, providing a stable and predictable output.

9. External Components: For the TPS61040DBVR to function properly, it requires specific external components like an inductor, input and output capacitors, and possibly feedback resistors. The selection of these components can influence the efficiency, stability, and performance of the boost converter.

10. Applications: Due to its ability to produce a high output voltage, the TPS61040DBVR is particularly suited for applications like:

- OLED or LCD bias supplies.

- White LED backlights for displays.

- Other applications requiring a high voltage from a single-cell Li-Ion or other low-voltage sources.

11. Efficiency: The TPS61040DBVR is designed for high efficiency, which is vital for battery-powered applications to prolong battery life.

For precise details, schematics, recommended operating conditions, application notes, and more regarding the TPS61040DBVR, always refer to the device's datasheet directly from Texas Instruments. The datasheet is the most comprehensive source of information for integrating and designing circuits around this IC.
