Part Number: UCC2889 Have several questions on the UCC2889. Using the UCC2889 as the controller in an offline bias supply in dual flyback configuration, similar to app note u-149. In the application, line voltage range is 600 - 1500V. Setting Ron so…
Part Number: UCC2889 Hi team,
Posting for a colleague:
Currently working on a bias supply using the UCC2889 controller running from 600-1200Vdc. I’ve run into some issues regarding the Line Voltage Detection and unexpectedly long on times.
The…
Is their a circuit model (schematic) available to open in Tina-TI available? There examples don't include much in the way of power circuit except the UCC28C42 . If there is a specific location for power circuit examples could someone point me to it…
Part Number: UCC28019A Other Parts Discussed in Thread: UCC2889 Hi,
For the VCC bias voltage souce connection, what's TI's suggestion?
example: voltage divider form HV? independent voltage source? or PFC choke?
Thank you.
