The recommended input capacitor value is 1uF to 10uF, with a voltage rating of at least 6.3V. A larger capacitor can help to reduce input voltage ripple and improve overall system stability.
To ensure stability, make sure to follow the recommended PCB layout guidelines, use a sufficient output capacitor (at least 2.2uF), and keep the input and output capacitors close to the device. Additionally, avoid using long traces and minimize the distance between the input and output pins.
The TPS70912DRVT can deliver up to 150mA of output current. However, the maximum output current may be limited by the input voltage, output voltage, and thermal considerations. Be sure to check the datasheet for specific details on output current capability.
The TPS70912DRVT is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. Be sure to check the datasheet for specific details on temperature-related specifications and derating.
The output voltage of the TPS70912DRVT is set by the resistor divider network connected to the FB pin. The output voltage can be calculated using the formula: Vout = 0.6V x (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
