TPS2561ADRCR datasheet by Texas Instruments

TPS2561ADRCR Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TPS2561ADRCR?
  The recommended layout and placement for the TPS2561ADRCR involves placing the device close to the load, using short and wide traces for power and ground, and keeping the input and output capacitors close to the device. A 4-layer PCB with a solid ground plane is recommended.
• How do I ensure the TPS2561ADRCR is stable and does not oscillate?
  To ensure stability, it is recommended to use a minimum output capacitance of 10uF, and to place the output capacitor close to the device. Additionally, the input capacitor should be placed close to the device and have a value of at least 1uF. The device should also be operated within its recommended operating conditions.
• What is the maximum input voltage that the TPS2561ADRCR can handle?
  The TPS2561ADRCR can handle input voltages up to 6.5V. However, it is recommended to operate the device within its recommended operating conditions, which is up to 5.5V, to ensure reliable operation and to prevent damage to the device.
• Can the TPS2561ADRCR be used in high-temperature applications?
  The TPS2561ADRCR is rated for operation up to 85°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the device's output current and voltage at high temperatures to ensure reliable operation.
• How do I calculate the output voltage of the TPS2561ADRCR?
  The output voltage of the TPS2561ADRCR can be calculated using the following formula: Vout = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors used in the feedback network. The output voltage can be adjusted by changing the values of R1 and R2.
