Instructions for NCP1252EDR2G

1. Input Voltage Connection:

   • Connect the input voltage (VIN) within the range of 4.5V to 28V. Ensure stable input supply to avoid damage or erratic behavior.

2. Output Configuration:

   • The output voltage is fixed at 5V. Verify that this matches your application requirements.

3. Load Connection:

   • Connect the load to the output terminals ensuring it does not exceed the maximum current rating of 2A continuously.

4. Capacitor Selection:

   • Choose input and output capacitors as specified in the datasheet to ensure stability and minimize ripple.

5. Thermal Management:

   • Ensure adequate heat dissipation, especially under high load conditions. Monitor the thermal shutdown threshold of 160°C.

6. PCB Layout Considerations:

   • Follow recommended PCB layout guidelines provided in the datasheet to optimize performance and reliability.

7. Protection Features:

   • The device includes protection against over-temperature conditions. Regularly check for proper operation within temperature limits.

8. Switching Frequency:

   • Operates typically at 1.3MHz. Design the external components considering this frequency to maintain efficiency and minimize noise.
