A good PCB layout for the TPS61160ADRVT involves placing the input and output capacitors close to the device, using a solid ground plane, and keeping the high-current paths short and wide. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
Choose input capacitors with a voltage rating of at least 2x the input voltage, and output capacitors with a voltage rating of at least 1.5x the output voltage. X5R or X7R ceramic capacitors are recommended for their low ESR and high reliability.
The TPS61160ADRVT is rated for operation from -40°C to 125°C, but the maximum ambient temperature range depends on the specific application and the device's power dissipation. Consult the thermal design considerations in the datasheet for more information.
Power dissipation can be calculated using the equation Pd = (Vin - Vout) x Iout x Efficiency. Consult the datasheet for the device's efficiency curve and thermal resistance values to estimate the power dissipation in your specific application.
The recommended input voltage range for the TPS61160ADRVT is 2.7V to 5.5V, but the device can operate from 2.3V to 5.5V. However, the output voltage and current capabilities may be reduced at lower input voltages.
