Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for high-frequency switching converters, such as keeping the power stage components close together, using a solid ground plane, and minimizing trace lengths and widths.
The selection of the inductor depends on the specific application requirements, such as the input voltage, output voltage, and output current. TI provides a list of recommended inductors in the datasheet, but engineers can also use online inductor selection tools or consult with inductor manufacturers to find the best fit for their design.
While the datasheet specifies an operating temperature range of -40°C to 125°C, the maximum ambient temperature for reliable operation depends on the specific application and the thermal design of the system. Engineers should consider factors such as airflow, heat sinking, and thermal interfaces to ensure reliable operation.
The BQ24750RHDR has built-in OVP and UVP features, but engineers may need to add external components to customize the protection thresholds. TI provides application notes and design examples to help engineers implement OVP and UVP in their designs.
The recommended input capacitor type and value depend on the specific application requirements, such as the input voltage and ripple current. TI recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, but engineers should consult the datasheet and application notes for more specific guidance.
