UCC287506DBVR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane on the bottom layer, and a split power plane on the top layer. The IC should be placed near the input capacitors, and the output diode should be placed near the output capacitors. A shielded inductor is also recommended to reduce EMI.
  • The compensation network should be designed to provide a phase margin of at least 45 degrees. A type-2 compensation network is recommended, with a zero at 1/3 of the switching frequency and a pole at 1/2 of the switching frequency. The values of the compensation components can be calculated using the equations provided in the datasheet.
  • The maximum allowed voltage on the VCC pin is 15V, but it is recommended to keep it below 12V to ensure reliable operation.
  • An overvoltage protection (OVP) circuit can be implemented using a zener diode and a resistor. An undervoltage protection (UVP) circuit can be implemented using a voltage supervisor IC.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. The capacitor should be placed as close as possible to the input pins of the IC.
