Instructions for Using K1CK024W

1. Input Voltage:

   • Ensure the input voltage is within the specified range of 4.5V to 36V.
   • Avoid exceeding the maximum input voltage to prevent damage to the device.

2. Output Voltage:

   • The K1CK024W provides a fixed output voltage of 5V. No external components are required to set this voltage.

3. Output Current:

   • The device can deliver a maximum continuous output current of 2.4A. Ensure that the load does not exceed this limit to avoid overheating or damage.

4. Efficiency:

   • The typical efficiency is 92%, which is achieved under nominal operating conditions. Monitor the efficiency to ensure optimal performance.

5. Switching Frequency:

   • The internal switching frequency is 1.5MHz. This helps in reducing the size of external components like inductors and capacitors.

6. Quiescent Current:

   • The quiescent current is 25渭A at no load. This low current consumption helps in extending battery life in portable applications.

7. Shutdown Current:

   • The shutdown current is 0.1渭A, allowing the device to be powered down with minimal power consumption.

8. Dropout Voltage:

   • The dropout voltage is 0.3V at full load. This ensures that the output voltage remains stable even when the input voltage is close to the output voltage.

9. Load Regulation:

   • The load regulation is 1% from 10% to 100% load, ensuring that the output voltage remains stable under varying load conditions.

10. Line Regulation:

    • The line regulation is 0.5%/V, indicating that the output voltage will change by 0.5% for every 1V change in input voltage.

11. Ripple Rejection:

    • The power supply rejection ratio (PSRR) is 70dB, which helps in filtering out input voltage ripple and noise.

12. Operating Temperature:

    • The device can operate within a temperature range of -40掳C to 125掳C. Ensure that the ambient temperature does not exceed these limits.

13. Storage Temperature:

    • The storage temperature range is -40掳C to 150掳C. Store the device in a dry and cool environment to maintain its performance.

14. Package Type:

    • The K1CK024W comes in a SOT-23-5 package, which is compact and suitable for surface mount applications.

Additional Notes:

• Always use appropriate heat sinking if the device is expected to operate at high temperatures or under heavy loads.
• Ensure proper PCB layout to minimize electromagnetic interference (EMI) and improve thermal performance.
• Refer to the datasheet for detailed information on pin configurations, recommended external components, and application circuits.
