Texas Instruments provides a recommended PCB layout in the TPS61301YFFR datasheet, but it's also important to follow general high-frequency layout guidelines, 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 input and output capacitors depends on the specific application requirements, such as the input voltage range, output voltage, and desired ripple and noise performance. TI provides guidelines for capacitor selection in the datasheet, but it's also important to consider factors such as capacitor ESR, ESL, and temperature coefficient.
The TPS61301YFFR is rated for operation from -40°C to 125°C, but the maximum ambient temperature range may be limited by the specific application and the thermal design of the system. It's important to consider the thermal performance of the device and the system as a whole to ensure reliable operation.
To ensure stability, it's important to follow the recommended component values and PCB layout guidelines in the datasheet. Additionally, it's important to consider the output capacitor ESR and the input voltage range to ensure that the device operates within its stable region. TI also provides a stability analysis tool to help designers evaluate the stability of their design.
The typical efficiency of the TPS61301YFFR depends on the specific application and operating conditions, but it can range from 85% to 95% depending on the input voltage, output voltage, and load current. TI provides efficiency curves in the datasheet to help designers estimate the efficiency of their design.
