The maximum input voltage that can be applied to the TPS70625DBVR is 12V, as specified in the datasheet. However, it's recommended to operate the device within the recommended input voltage range of 2.7V to 10V for optimal performance and reliability.
To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines provided in the datasheet. Additionally, using a high-quality output capacitor with a low equivalent series resistance (ESR) and a sufficient capacitance value can help maintain output voltage stability.
The minimum input capacitance required for the TPS70625DBVR is 1uF, as specified in the datasheet. However, it's recommended to use a higher capacitance value, such as 4.7uF or 10uF, to ensure stable operation and minimize input voltage ripple.
The TPS70625DBVR is rated for operation up to 125°C, but it's essential to consider the device's power dissipation and thermal management when operating in high-temperature environments. Ensure that the device is properly heat-sinked and follow the recommended thermal design guidelines to prevent overheating.
The output voltage of the TPS70625DBVR can be calculated using the following formula: Vout = (R1 / R2) * (Vref), where R1 and R2 are the resistors connected to the FB pin, and Vref is the internal reference voltage (1.25V).
