The maximum capacitance depends on the application and the desired output voltage ripple. As a general guideline, TI recommends using capacitors with a capacitance value between 10uF to 100uF. However, it's essential to perform a thorough stability analysis to ensure the capacitor value meets the specific application requirements.
To ensure stability, follow the layout guidelines in the datasheet, keep the input and output capacitors close to the device, and use a low-ESR capacitor. Additionally, ensure the output voltage is within the recommended range, and the input voltage is above the minimum specified value. If oscillations occur, try adding a small ceramic capacitor (1nF to 10nF) between the VOUT and GND pins.
The maximum input voltage for the TPS2064CDGNR-2 is 5.5V. Exceeding this voltage may cause damage to the device. It's essential to ensure the input voltage remains within the recommended operating range to maintain device reliability and performance.
The TPS2064CDGNR-2 is rated for operation up to 85°C. However, the device's performance and reliability may degrade at higher temperatures. If your application requires operation above 85°C, consider using a different device or implementing additional thermal management measures.
The output voltage of the TPS2064CDGNR-2 is set by the resistor divider network connected to the FB pin. Use the following formula to calculate the output voltage: VOUT = 0.6V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
