Instructions for PS2801-4-F3

  1. Power Supply Connection:

    • Connect the input voltage (V_IN) to the power supply within the specified range (4.5V to 26V).
    • Ensure the output voltage (V_OUT) is connected to the load, which should be within the specified range (3.0V to 5.5V).
  2. Output Current:

    • The device can provide a typical output current of 1.0A with a maximum of 1.5A. Ensure the load does not exceed this limit to avoid damage.
  3. Efficiency:

    • The efficiency of the device is typically 90%. This value can vary depending on the input and output conditions.
  4. Thermal Management:

    • The thermal resistance (θJA) is 50°C/W. Ensure adequate heat dissipation to keep the operating temperature within the specified range (-40°C to 125°C).
  5. Operating Conditions:

    • The device operates within a wide temperature range (-40°C to 125°C). Store the device within the storage temperature range (-65°C to 150°C).
  6. Regulation:

    • The load regulation and line regulation are both typically 1%. This ensures stable output voltage under varying load and input conditions.
  7. Dropout Voltage:

    • The dropout voltage is 1.2V. Ensure the input voltage is at least 1.2V higher than the desired output voltage to maintain regulation.
  8. Quiescent Current:

    • The quiescent current is typically 30μA. This low current draw helps in minimizing power consumption during no-load conditions.
  9. Switching Frequency:

    • The switching frequency is 750kHz. This high frequency allows for smaller external components and faster transient response.
  10. Storage and Handling:

    • Store the device in a dry, cool place away from direct sunlight and sources of heat.
    • Handle the device with care to avoid mechanical damage or electrostatic discharge (ESD).

By following these parameters and instructions, you can ensure optimal performance and longevity of the PS2801-4-F3.
