Instructions for Use

1. Input Connection:

   • Connect the input voltage (VIN) to the positive terminal and ground (GND) to the negative terminal.
   • Ensure the input voltage is within the specified range (4.5V to 60V).

2. Output Connection:

   • Connect the output voltage (VOUT) to the load and ground (GND) to the common ground.
   • The output voltage is fixed at 12V.

3. Thermal Management:

   • Ensure proper heat dissipation to maintain the operating temperature within the specified range (-40掳C to 85掳C).
   • The device will shut down if the temperature exceeds 160掳C.

4. Load Regulation:

   • The load regulation is 卤1%, ensuring stable output voltage over varying load conditions.

5. Line Regulation:

   • The line regulation is 卤1%, ensuring stable output voltage over varying input voltages.

6. Ripple Voltage:

   • The ripple voltage should not exceed 50mVpp under normal operating conditions.

7. Efficiency:

   • The efficiency is typically 85% under nominal conditions.

8. Storage:

   • Store the device in a dry environment with temperatures between -40掳C and 125掳C.

9. Switching Frequency:

   • The switching frequency is fixed at 300kHz.

10. Quiescent Current:

    • The quiescent current is typically 2.5mA.

11. Safety:

    • Always follow proper electrical safety procedures when handling and connecting the device.
    • Avoid short circuits and ensure all connections are secure.

12. Testing:

    • Before deploying the device, test it under expected operating conditions to ensure proper functionality.
