A good PCB layout for the BQ24630RGET involves keeping the high-current paths short and wide, using a solid ground plane, and placing the input capacitors close to the device. TI provides a recommended layout in the datasheet and application notes.
When selecting an inductor for the BQ24630RGET, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating above the peak current of the converter, and a DC resistance that minimizes power loss.
The BQ24630RGET is rated for operation up to 105°C ambient temperature, but the device's junction temperature should not exceed 125°C. Ensure proper thermal design and heat sinking to maintain a safe operating temperature.
While the BQ24630RGET is designed for 12V and 24V input voltages, it can be used with other input voltages with some modifications. However, this may require adjustments to the component values and PCB layout, and may affect the device's performance and efficiency.
To troubleshoot issues with the BQ24630RGET, start by verifying the input voltage, checking for proper component installation and PCB layout, and ensuring that the device is properly configured. Use an oscilloscope to monitor the device's internal signals and output voltage.
