    FAQs

    What is TPS54240DGQ?

    The TPS54240DGQ is a synchronous step-down DC-DC converter designed by Texas Instruments. It is ideal for applications requiring efficient power conversion with high voltage input capability, such as industrial control systems, automotive electronics, and battery-powered devices.

    How Does TPS54240DGQ Work?

    The TPS54240DGQ operates by converting a higher input voltage to a lower regulated output voltage with high efficiency. It utilizes a synchronous buck topology to step down the voltage and regulate the output. The converter features pulse-width modulation (PWM) control for precise voltage regulation and current limiting for overload protection.

    How Many Pins does TPS54240DGQ have and What are the Functions of the Pinout Configuration?

    The TPS54240DGQ is housed in a 10-pin MSOP (Mini Small Outline Package) package. The pinout configuration includes:

    • SW: Switching node for the power stage.
    • FB: Feedback pin for output voltage regulation.
    • EN: Enable pin for controlling the converter operation.
    • PGND: Power ground pin.
    • PH: Phase compensation pin.
    • VFB: Internal feedback voltage pin.
    • VSENSE: Current sensing pin.
    • COMP: External compensation pin.
    • DRV: Gate driver pin for the MOSFET.
    • VOUT: Regulated output voltage.

    What are the Pros and Cons of TPS54240DGQ?

    Pros:

    • High Efficiency: Provides efficient power conversion, reducing power losses.
    • Wide Input Voltage Range: Suitable for applications with varying input voltage levels.
    • Current Limiting: Offers overload protection with current limiting capability.
    • Compact Package: 10-pin MSOP package is compact and space-efficient.
    • Adjustable Output Voltage: Allows for flexibility in output voltage selection.

    Cons:

    • External Components: May require additional external components for specific application requirements.
    • Complexity: Synchronous buck converters like the TPS54240DGQ may require careful design considerations for optimal performance.
    • Heat Dissipation: High-efficiency converters may generate some heat under heavy load conditions.

    Are There Any Equivalents/Alternatives to TPS54240DGQ for Recommendation?

    • The LM2675 from Texas Instruments is a similar synchronous step-down converter with slightly different features.
    • Alternatives to the TPS54240DGQ include the MP2307 from Monolithic Power Systems and the LT1370 from Analog Devices.
