Key Document


The PMP20106 reference design uses the UCC28880 integrated FET PWM controller for a -5V/50mA, 3.3V/100mA, and 16V/100mA triple-output bias supply with high voltage DC input (270VDC to 410VDC input). With 3.3V well regulated, 16V output voltage falls in between 9.35V and 16.99V and -5V output voltage falls in between -3.05V to -6.25V.

  • 400VDC input to -5V/50mA, 3.3V/100mA, and 16V/100mA triple-output
  • 1.2" x 2.7" board dimension
  • UCC28880 low cost FET integrated PWM controller
  • Less than 400mW no load power consumption
  • Cross regulation tested
