TPS922053DYYR Frequently Asked Questions (FAQs)

  • Texas Instruments provides a recommended PCB layout in the TPS922053DYYR evaluation module documentation, which includes a thermal pad connection to the ground plane and a copper pour on the top and bottom layers to dissipate heat.
  • To ensure reliable startup and shutdown, it's essential to follow the recommended soft-start and shutdown procedures outlined in the datasheet, including the use of a soft-start capacitor and a shutdown pin capacitor.
  • The maximum allowable voltage on the VIN pin during startup is 5.5V, as specified in the datasheet. Exceeding this voltage may damage the device.
  • To optimize output voltage ripple and noise, use a low-ESR output capacitor, minimize the output capacitor's equivalent series resistance (ESR), and consider adding a filter capacitor in parallel with the output capacitor.
  • Texas Instruments recommends using a low-ESR, X5R or X7R ceramic capacitor with a value of 10uF to 22uF for the input capacitor, depending on the specific application requirements.
