Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines 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.
The selection of the inductor depends on the output current, output voltage, and switching frequency. 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 SLVAE04.
The maximum input voltage rating for the TPS61045DRBTG4 is 5.5V, but it's recommended to operate the device within the recommended input voltage range of 2.7V to 5.5V to ensure optimal performance and reliability.
The output voltage of the TPS61045DRBTG4 can be adjusted by using a resistive divider network between the output and the feedback pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
The thermal shutdown temperature of the TPS61045DRBTG4 is typically around 150°C, but it can vary depending on the specific device and operating conditions. It's recommended to consult the datasheet and application notes for more information on thermal management.
