Part Number: UCC24612 Other Parts Discussed in Thread: UCC28631 , UCC28630 Hi all,
Is it possible to use UCC24612-1 as S.R. for UCC28631 CC mode ?

Thank you!
Hi Jayaprakash,
We currently do not support multi-output power supply designs in new WEBENCH power designer tool.
Alternatively, you could design each output separately.
Could you please let us know if application for DC to DC converter is isolated…
Hi Harish
Sorry for late answer but I held this project because of other priorities.
Large output capacitors did not solved this issue, I must redesign layout and maybe change transformer but this will take some time.

Part Number: UCC28630EVM-572 Other Parts Discussed in Thread: UCC28631 , UCC28630 , UCC28634 Dear TI,
I am trying to design a housekeeping power supply for one of our products.
Requirement:
Input: 260 Vdc to 710 Vdc
Output: 12 V @ 1.5 A max. …
Hi Bernat,
Thanks for the query.
The restart of Vdd is normal in UCC28634 because there is a fault which needs to be addressed before controller starts switching.
Could you please share the pdf schematic, input output system specs and transformer…
Simon,
I will comment on the UCC28631 Flyback portion of the schematic, and one of my colleagues will respond regarding the UCC28063 boost PFC portion.
- R16 connecting to HV pin should be 2 resistors in series since most SMT resistors are limited…
Great, thank you! Could you please suggest your technical authors adding an example without the resistor or at least emphasising the fact that it is solely for discharge timing and has no purpose during the startup phase, except for obviously slowing…
Other Parts Discussed in Thread: UCC28630 Greetings,
I have rebuilt a power supply based on the UCC28631 , creating several supplies based on working prototypes with modifications from this post . However, I am having trouble with startup again, after…
Hi, Leela,
TI provides the parts with 700V start up capability. Below is the list of the parts that integrated 700V start up circuit
Without integrated power MOSFET
UCC28710, UCC28711, UCC28712, UCC28713, UCC28730, UCC28740, UCC28630, UCC28631,…
As Bing noted above, if the applications requires PFC when the input power goes above 75 W, then this will set the upper power limit capability of the Flyback power stage.
Some applications do not require PFC, even if the power is > 75 W. In these cases…
