Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended 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. In general, low-ESR capacitors with high ripple current ratings are recommended. The datasheet provides some guidance on capacitor selection, but it's also recommended to consult the capacitor manufacturer's datasheet and application notes.
The TPS61162AYFFR is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the thermal design of the system. It's recommended to consult the thermal design guidelines in the datasheet and to perform thermal simulations to ensure the device operates within its specified temperature range.
To ensure stability, it's recommended to follow the guidelines in the datasheet for component selection and PCB layout. Additionally, it's recommended to add a small ceramic capacitor (e.g. 10nF) between the VIN and EN pins to filter out noise and prevent oscillation.
The recommended input voltage range for the TPS61162AYFFR is 2.7V to 5.5V, but the device can operate from 2.3V to 5.5V. However, the output voltage regulation and efficiency may be affected at lower input voltages.
