TPS65170RHDT Frequently Asked Questions (FAQs)
Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general best practices for switching regulator layout, such as keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce EMI.
The datasheet provides a list of recommended inductors, but you can also use the following guidelines: choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (typically between 1-10uH). You can also use online inductor selection tools or consult with the inductor manufacturer for specific recommendations.
The datasheet specifies a maximum input voltage of 18V, but it's important to note that the device can handle transient voltages up to 22V for short durations (less than 100ms). However, it's recommended to keep the input voltage below 18V to ensure reliable operation and prevent damage to the device.
The output voltage of the TPS65170RHDT can be adjusted by changing the resistor divider network connected to the FB pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage. You can also use online calculators or simulation tools to simplify the process.
The thermal derating of the TPS65170RHDT is specified in the datasheet, and it indicates the reduction in output current capability as the device temperature increases. To ensure reliable operation, it's essential to consider the thermal derating when designing the system, especially in high-temperature environments or high-current applications.
