The maximum input voltage that can be applied to the TPS54672PWP is 6.5V, as specified in the datasheet. However, it's recommended to keep the input voltage below 6V to ensure reliable operation and to prevent damage to the device.
To ensure stability, it's essential to follow the layout guidelines provided in the datasheet, including keeping the input and output capacitors close to the device, using a low-ESR output capacitor, and minimizing the loop area of the power traces. Additionally, the datasheet provides a recommended compensation network that should be used to ensure stability.
The minimum output voltage that can be achieved with the TPS54672PWP is 0.7V, as specified in the datasheet. However, the output voltage can be adjusted down to 0.6V by using an external resistor divider network.
The TPS54672PWP is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It's essential to follow the thermal design guidelines provided in the datasheet and to ensure that the device is properly heatsinked to prevent overheating.
The power dissipation of the TPS54672PWP can be calculated using the equation: Pd = (Vin - Vout) x Iout x Efficiency. The datasheet provides the efficiency curve, and the input and output voltages and currents can be measured or calculated based on the application requirements.
