Instructions for Use:

1. Supply Voltage (Vcc):

   • Ensure the supply voltage is within the specified range (2.7V to 5.5V) to avoid damage or improper operation.

2. Output Current (Iout):

   • The device can provide up to 250mA continuously. For higher currents, ensure proper heat dissipation.

3. Quiescent Current (Iq):

   • The quiescent current is very low (1渭A to 3渭A), making it suitable for battery-powered applications.

4. Efficiency (畏):

   • The efficiency is typically 90%, which helps in reducing power loss and heat generation.

5. Switching Frequency (fsw):

   • The internal switching frequency is 1.5MHz, which allows for smaller external components.

6. Dropout Voltage (Vdo):

   • The dropout voltage is typically 0.3V, ensuring stable operation even when the input voltage is close to the output voltage.

7. Output Ripple (Vripple):

   • The output ripple is between 30mVpp and 50mVpp. Use appropriate filtering capacitors to minimize ripple if necessary.

8. Thermal Shutdown (TSD):

   • The device will shut down at approximately 160掳C to protect against overheating. Ensure adequate cooling for high-power applications.

9. Operating Temperature (Topr):

   • The device operates reliably from -40掳C to 125掳C. Avoid exposing the device to temperatures outside this range during operation.

10. Storage Temperature (Tstg):

    • Store the device between -65掳C and 150掳C to prevent damage due to extreme temperatures.

Additional Notes:

• PCB Layout:
  • Ensure proper PCB layout with short traces and adequate ground planes to minimize noise and improve stability.
• Capacitors:
  • Use high-quality ceramic capacitors for input and output filtering to maintain performance and reliability.
• Inductor Selection:
  • Choose an inductor that can handle the maximum output current and has a low DC resistance to minimize losses.
