TPS61085PWRG4 Frequently Asked Questions (FAQs)
Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general high-frequency layout guidelines, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths.
The selection of the inductor depends on the output current, switching frequency, and output voltage. TI provides an inductor selection guide in the datasheet, but it's also recommended to consult with inductor manufacturers and consider factors such as inductor core material, size, and saturation current.
The TPS61085PWRG4 is rated for operation up to 125°C, but the maximum ambient temperature for reliable operation depends on the specific application and thermal design. It's recommended to consider the thermal derating curves in the datasheet and ensure proper heat sinking and airflow in the system.
To ensure EMC compliance, it's recommended to follow proper PCB layout and shielding techniques, use a common-mode choke or ferrite bead on the input, and consider adding EMI filters or shielding on the output. TI also provides EMC guidelines in the datasheet and application notes.
The recommended input capacitor type is a low-ESR ceramic capacitor, such as an X5R or X7R type. The value depends on the input voltage and output current, but a typical value is 10-22uF. It's also recommended to consider the capacitor's voltage rating, temperature coefficient, and ripple current rating.
