The maximum input voltage that can be applied to the TPS74301KTWT is 15V, but it's recommended to operate within the specified input voltage range of 2.7V to 12V 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, including the use of a suitable output capacitor and proper PCB layout.
The minimum input capacitance required for the TPS74301KTWT is 1uF, but it's recommended to use a higher value (e.g., 4.7uF) to ensure stable operation and minimize input voltage ripple.
The TPS74301KTWT is rated for operation up to 125°C, but it's essential to consider the thermal design and heat dissipation in your system to ensure reliable operation. You may need to add thermal management components or use a heat sink to keep the device within its operating temperature range.
To calculate the power dissipation of the TPS74301KTWT, you need to consider the input voltage, output voltage, output current, and quiescent current. You can use the formula provided in the datasheet or consult with a Texas Instruments application engineer for guidance.
