UCC28701DBVT datasheet by Texas Instruments

UCC28701DBVT Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of the UCC28701DBVT?
  A good PCB layout for the UCC28701DBVT involves keeping the high-frequency switching nodes (e.g., SW and VIN) away from sensitive analog nodes (e.g., FB and COMP). Use a solid ground plane, and keep the power traces short and wide. TI provides a recommended PCB layout in the datasheet and application notes.
• How do I choose the right inductor value for my application?
  The inductor value depends on the output voltage, input voltage, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet. You can also use TI's WEBENCH online design tool to help select the optimal inductor value.
• What is the maximum ambient temperature range for the UCC28701DBVT?
  The UCC28701DBVT is rated for operation from -40°C to 125°C. However, the maximum ambient temperature range may be limited by the specific application and the thermal design of the system.
• How do I ensure the UCC28701DBVT is stable and doesn't oscillate?
  To ensure stability, follow the compensation network design guidelines in the datasheet. Use a type-III compensation network, and adjust the values based on the output voltage and load current. You can also use TI's compensation network design tool to help with the design.
• What is the maximum output current capability of the UCC28701DBVT?
  The UCC28701DBVT can deliver up to 10A of output current, depending on the input voltage, output voltage, and thermal design of the system. However, the maximum output current may be limited by the inductor and output capacitor selection.
