UCC28600D Frequently Asked Questions (FAQs)

  • TI recommends a compact layout with the UCC28600D placed close to the input capacitors and the output inductor. The input capacitors should be placed as close as possible to the VIN pin, and the output inductor should be placed close to the SW pin. Additionally, a solid ground plane and a separate power plane can help reduce EMI.
  • The compensation network can be optimized by using the TI-provided compensation calculator tool or by following the guidelines in the datasheet. The goal is to achieve a stable loop gain of around 10-15 dB at the crossover frequency. The compensation network should be adjusted to achieve a phase margin of at least 45 degrees.
  • The maximum allowed voltage on the EN pin is 6V. To ensure it is not exceeded, a voltage divider or a zener diode can be used to limit the voltage to the EN pin. Additionally, a pull-down resistor can be used to ensure the EN pin is not floating.
  • The UCC28600D has a built-in OCP feature that limits the output current to prevent damage. To handle OCP, the designer should ensure that the output current is monitored and limited to a safe value. The OCP threshold can be adjusted by changing the value of the RSENSE resistor.
  • TI recommends using a low-ESR ceramic capacitor with a value of at least 10uF and a voltage rating of at least 1.5 times the input voltage. The capacitor should be placed as close as possible to the VIN pin.
