TPS54680PWP datasheet by Texas Instruments

TPS54680PWP Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the TPS54680PWP?
  The maximum input voltage that can be applied to the TPS54680PWP is 6.5V. Exceeding this voltage may damage the device.
• How do I ensure the TPS54680PWP 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 at least 10uF and placed close to the input pin.
• What is the minimum input voltage required for the TPS54680PWP to operate?
  The minimum input voltage required for the TPS54680PWP to operate is 2.5V. However, the device can operate down to 2.2V with reduced performance.
• Can I use the TPS54680PWP in a high-temperature environment?
  The TPS54680PWP is rated for operation up to 125°C. However, the device's performance may degrade at high temperatures, and the output voltage may drop. It is recommended to derate the output current at high temperatures.
• How do I synchronize the switching frequency of multiple TPS54680PWP devices?
  To synchronize the switching frequency of multiple TPS54680PWP devices, connect the SYNC pin of each device to a common clock signal. The SYNC pin can be driven by an external clock signal or by the clock output of one of the devices.
