Description

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
