TPS65560RGTR datasheet by Texas Instruments

TPS65560RGTR Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance?
  Texas Instruments provides a recommended PCB layout in the TPS65560RGTR datasheet (Section 10.2) and in the TPS65560RGTR Evaluation Module User's Guide (SLUU444). It's essential to follow these guidelines to minimize noise, ensure proper thermal management, and optimize performance.
• How do I select the correct input capacitor values?
  The input capacitor values depend on the input voltage, output voltage, and desired output ripple. TI recommends using X5R or X7R ceramic capacitors with a minimum capacitance of 10uF and a voltage rating of at least 1.5 times the maximum input voltage. Refer to the datasheet (Section 7.3.1) for more information.
• What is the maximum output current capability of the TPS65560RGTR?
  The TPS65560RGTR can deliver up to 2A of output current. However, the maximum output current is dependent on the input voltage, output voltage, and thermal conditions. Refer to the datasheet (Section 6.3) for more information on output current capability and thermal derating.
• How do I implement overvoltage protection (OVP) and undervoltage protection (UVP)?
  The TPS65560RGTR has built-in OVP and UVP features. To implement these features, connect the OVP and UVP pins to the desired voltage threshold using resistive dividers. Refer to the datasheet (Section 7.3.4) for more information on OVP and UVP configuration.
• What is the purpose of the EN pin, and how do I use it?
  The EN (Enable) pin is used to enable or disable the device. When the EN pin is pulled high, the device is enabled, and when it's pulled low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device during shutdown or low-power modes.
