Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow 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. TI provides an inductor selection guide in the datasheet, and online tools such as the TI Inductor Selection Tool can also be used to find a suitable inductor.
The maximum input voltage rating for the TPS61061YZFT is 18V, but it's recommended to operate the device within the recommended input voltage range of 3.5V to 15V to ensure reliable operation and to prevent damage to the device.
The output voltage of the TPS61061YZFT 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.
The EN (enable) pin is used to turn the device on or off. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device when it's not in use.
