Instructions for NCP1587ADR2G

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 40V.
   • Use appropriate input capacitors to stabilize the input voltage.

2. Output Voltage (VOUT):

   • Set the output voltage using external resistors according to the formula provided in the datasheet.
   • Use a low ESR output capacitor to filter the output and ensure stability.

3. Output Current (IOUT):

   • The device can deliver up to 3A, but typical operation is at 2A.
   • Ensure proper heat dissipation if operating at higher currents.

4. Quiescent Current (IQ):

   • The quiescent current is typically 65μA, which helps in maintaining high efficiency even at low loads.

5. Shutdown Current (ISD):

   • When the shutdown pin is pulled low, the device enters a low-power mode with a shutdown current of approximately 1μA.

6. Switching Frequency (fSW):

   • The switching frequency can be adjusted between 200kHz and 2000kHz using an external resistor.
   • Higher frequencies reduce the size of external components but may increase switching losses.

7. Efficiency (η):

   • The typical efficiency is 92%, which can be optimized by selecting appropriate inductors and output capacitors.

8. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 300mV, allowing the device to operate efficiently even when the input voltage is close to the output voltage.

9. Thermal Shutdown Temperature (TSD):

   • The device will shut down if the junction temperature exceeds 160°C to prevent damage.

10. Operating Temperature (TOPR):

    • The device is designed to operate over a wide temperature range from -40°C to 125°C.

11. Storage Temperature (TSTG):

    • Store the device in a dry environment with temperatures ranging from -65°C to 150°C.

12. PCB Layout:

    • Follow the recommended PCB layout guidelines to minimize parasitic effects and ensure optimal performance.
    • Place the input and output capacitors as close as possible to the device to reduce noise and improve stability.

13. Protection Features:

    • The device includes overcurrent protection, thermal shutdown, and undervoltage lockout to protect against various fault conditions.

14. Application Notes:

    • Refer to the application notes and datasheet for detailed design considerations, including component selection and layout recommendations.
