Instructions for BD9289F-HVGE2

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 4.5V to 36V for reliable operation.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted according to your application needs using external components like resistors. Refer to the datasheet for specific resistor values and configurations.

3. Output Current (IOUT):

   • The device supports a continuous output current up to 2.5A. Ensure that the load does not exceed this limit to avoid damage or overheating.

4. Switching Frequency (fSW):

   • The default switching frequency is set at 2.2MHz. This can be adjusted if necessary through an external component or configuration.

5. Quiescent Current (IQ):

   • At an input voltage of 12V, the quiescent current is typically around 30μA. This parameter helps in understanding the power consumption in standby mode.

6. Dropout Voltage (VDROPOUT):

   • When operating at full load with an input voltage of 12V, the dropout voltage is approximately 0.8V. This is important for applications where minimizing voltage drop is critical.

7. Efficiency (η):

   • For optimal efficiency, operate the device under conditions where it achieves its highest efficiency rating, such as VIN = 12V, VOUT = 5V, and IOUT = 1A, achieving up to 95%.

8. Operating and Storage Temperature:

   • The operating junction temperature should be kept between -40°C and 125°C. The storage temperature range is from -40°C to 150°C.

For detailed setup and more specific parameters, refer to the manufacturer's datasheet.
