Instructions for STRW6252

1. Input Connection:

   • Connect the positive terminal of the input voltage to the VIN pin.
   • Connect the negative terminal of the input voltage to the GND pin.

2. Output Connection:

   • Connect the positive terminal of the load to the VOUT pin.
   • Connect the negative terminal of the load to the GND pin.

3. Enable/Shutdown:

   • To enable the device, connect the EN pin to a voltage greater than 1.2V.
   • To shut down the device, connect the EN pin to GND or leave it floating.

4. Capacitor Selection:

   • Use a ceramic capacitor with a minimum capacitance of 10渭F for the input (CIN).
   • Use a ceramic capacitor with a minimum capacitance of 22渭F for the output (COUT).

5. Inductor Selection:

   • Choose an inductor with a value between 4.7渭H and 10渭H, depending on the desired ripple current and efficiency.

6. Thermal Management:

   • Ensure adequate heat dissipation by mounting the device on a heatsink or a PCB with sufficient copper area.

7. PCB Layout:

   • Keep the input and output capacitors as close as possible to the respective pins.
   • Use wide traces for power connections to minimize voltage drops and heating.

8. Overvoltage Protection:

   • Consider adding overvoltage protection circuits to protect the load from transient voltages.

9. Short-Circuit Protection:

   • The device has built-in short-circuit protection, but ensure the load does not exceed the maximum current rating.

10. Testing:

    • Before finalizing the design, test the circuit under various conditions to ensure stable operation and compliance with specifications.
