Instructions for Use:

1. Input Connection:

   • Connect the input voltage (V_IN) to the input pin of the PSD813F2A-90JI.
   • Ensure the input voltage is within the range of 4.5V to 28V.

2. Output Connection:

   • Connect the output pin to the load requiring a regulated 3.3V supply.
   • The maximum continuous output current is 3A.

3. Ground Connection:

   • Connect the ground pins of both the input and output to a common ground.

4. Capacitors:

   • Place a 10μF ceramic capacitor close to the input pin to stabilize the input voltage.
   • Place a 10μF ceramic capacitor close to the output pin to filter the output voltage.

5. Thermal Management:

   • Ensure adequate heat dissipation, especially when operating at high output currents.
   • The device can operate in ambient temperatures from -40°C to 85°C.

6. Efficiency:

   • The efficiency is optimized at higher output currents, with a typical efficiency of 90% at 3A.

7. Protection Features:

   • The device includes overcurrent and thermal shutdown protection to prevent damage under fault conditions.

8. Storage:

   • Store the device in a dry environment within the temperature range of -65°C to 150°C.

9. Handling:

   • Handle the device with care to avoid damage to the pins and internal components.
   • Follow standard ESD (Electrostatic Discharge) precautions to prevent damage.
