    LM2576HVT-ADJ Typical application Circuitry

    LM2576HVT-ADJ

    The LM2576HVT-ADJ is a variant of the versatile LM2576 series, a family of regulator integrated circuits specifically designed for buck (step-down) voltage conversion. This adjustable version facilitates the customization of the output voltage as required for a particular application, within a specified range that is governed by external resistive components.

    1. Input (Pin 1): This pin serves as the entry point for the input voltage, which is to be stepped down by the LM2576HVT-ADJ. An input capacitor should be connected to this pin to ensure smooth operation by mitigating voltage fluctuations and spikes.

    2. Output (Pin 2): At this pin, the controlled output voltage is supplied. Key to its stable operation is an inductor, situated between this pin and the load, and a freewheeling diode that recirculates current when the internal switch is open. Additionally, an output capacitor is necessary to smooth out the voltage ripple.

    3. Feedback (Pin 3): This pin is critical for setting the output voltage for the LM2576HVT-ADJ. A resistive voltage divider is connected to this pin, with the other end tied to the output and the other to ground. The LM2576HVT-ADJ modulates its internal components to maintain a constant voltage at the feedback pin, relative to a reference voltage.

    4. On/Off (Pin 4): The functionality of the LM2576HVT-ADJ can be toggled using this pin. Driving it low deactivates the regulator, whereas connecting it to a high signal or leaving it open ensures the device remains operational.

    5. Ground (Pin 5): As the common reference for all operations, this pin should be connected to the system ground. It plays a significant role in the regulation process of the LM2576HVT-ADJ.

    Integrating the LM2576HVT-ADJ into a power supply circuit requires adherence to the guidelines provided in the datasheet, especially concerning the selection of inductors, diodes, and capacitors that match the intended output specifications. The physical layout of these components on a printed circuit board is equally important to achieve optimal performance and reliability from the LM2576HVT-ADJ.
