Texas Instruments provides a recommended PCB layout in the TPS82677SIPR datasheet, but it's also recommended to follow the general guidelines for switching regulator layout, such as keeping the input and output capacitors close to the IC, and using a solid ground plane to reduce noise and EMI.
The selection of the inductor depends on the output current, switching frequency, and output voltage ripple requirements. Texas Instruments provides a list of recommended inductors in the datasheet, but you can also use the inductor selection guide provided in the application note SLVA477.
The TPS82677SIPR has an absolute maximum input voltage rating of 6.5V, but the recommended operating input voltage range is 2.7V to 5.5V. Exceeding the absolute maximum rating can damage the device.
The output voltage of the TPS82677SIPR can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
The thermal shutdown temperature of the TPS82677SIPR is typically around 150°C, but it can vary depending on the specific device and operating conditions. The device will automatically shut down when the junction temperature exceeds this threshold to prevent damage.
