Instructions for BD9886FV-E2

1. Input Voltage Setup:

   • Ensure the input voltage is within the operating range of 4.5V to 28V.

2. Output Voltage Configuration:

   • Adjust the output voltage using external resistors according to the datasheet formula: VOUT = VREF * (1 + R1/R2).

3. Switching Frequency Adjustment:

   • The switching frequency can be adjusted by changing the value of an external resistor connected to the RT pin.

4. Thermal Management:

   • Monitor the device temperature and ensure it does not exceed the thermal shutdown threshold of 160°C.

5. Efficiency Optimization:

   • For optimal efficiency, operate within recommended input/output voltage ranges and load currents.

6. Quiescent Current Minimization:

   • To minimize quiescent current, avoid unnecessary loads and use the device in low-power modes when applicable.

7. Protection Features:

   • The device includes protection features such as overcurrent protection, short-circuit protection, and thermal shutdown. Verify these are functioning correctly during operation.

8. Capacitor Selection:

   • Choose input and output capacitors with appropriate ratings to stabilize the power supply and reduce ripple.

9. Layout Considerations:

   • Pay attention to PCB layout guidelines provided in the datasheet to ensure reliable performance and minimize noise.
