  • Page 7: Circuit Description

    Circuit Description www.ti.com Circuit Description The UCC28880EVM-616 is a non-isolated AC-to-DC high-side buck configuration with direct feedback. The EVM, on the input side, has a half-wave rectifier assembled for rectification of AC-to-DC, followed by an EMI filter. The pre-set output voltage is set to ~13 V (typical) if jumper J3 is not connected, or ~5 V (typical) when the jumper is inserted.
  • Page 8 With 5 V output, the preload is ~400 µA. A load of up to 100 mA can be applied to the output. The design of UCC28880EVM-616 is optimized for 13-V output setting. For 5-V setting, there is additional room for optimization when factors such as audible noise, output voltage ripple, stand-by power etc are considered.
  • Page 9 Figure 2 shows the basic test setup recommended to evaluate the UCC28880EVM-616. Start by applying a low DC voltage (~15 V to 20 V) into the AC input (P1). When connected correctly the output voltage is regulated to ~13 V (positive with respect to GND). Once correct output level is obtained, increase the input voltage to the desired level.

  • Page 10: Test Equipment

    Load: The UCC28880EVM-616 is capable of delivering 100 mA of output current. 50 Ω, at 1 W is the minimum value of load resistance for the 5-V output and 130 Ω at 5 W is the minimum value of load resistance for the 13-V output.
