TPS65279DAPR Frequently Asked Questions (FAQs)
Texas Instruments provides a recommended layout and placement guide in the TPS65279DAPR datasheet, but it's also recommended to follow the general guidelines for switching regulators, such as keeping the input and output capacitors close to the device, and using a solid ground plane to reduce noise and EMI.
The selection of the inductor depends on the specific application requirements, such as the output voltage, current, and frequency. Texas Instruments provides a list of recommended inductors in the datasheet, but it's also recommended to consult the inductor manufacturer's datasheet and to consider factors such as inductor core material, size, and saturation current.
The TPS65279DAPR has an absolute maximum input voltage rating of 18V, but the recommended operating input voltage range is 6.5V to 14V. Exceeding the maximum input voltage can damage the device.
The output voltage of the TPS65279DAPR can be adjusted by changing the resistive divider ratio of the feedback resistors (RFBT and RFBG). The output voltage can be calculated using the formula provided in the datasheet, and the resistors can be selected using a resistor calculator or by consulting the datasheet.
The TPS65279DAPR has a thermal derating curve provided in the datasheet, which shows the maximum output current that the device can handle at different ambient temperatures. The device must be derated to prevent overheating and damage.
