Part Number: UCC25800EVM-1 Other Parts Discussed in Thread: TL431 Hi team,
May I modify the parameter from 18V,-5V to +12,-12V on the EVM?
I try to modify it. but when no-load condition that output voltage is stable.
I try to adjust output load up each…
Part Number: UCC25800EVM-1 Other Parts Discussed in Thread: TL431 Hi TI team,
Could you please let me know the function of Q1 transistor in below schematic of biasing circuit?
In my measurement and simulation, there are always a drop voltage of 0.7V -…
Part Number: UCC25800EVM-1 Other Parts Discussed in Thread: TL431 Dear TI team,
Below is the schematic for regulating both negative and positive rails of isolated bias supply from TI reference design "Using the UCC25800EVM-037 2-W LLC Converter for…
Hi Patrick,
a) Options for positive and negative rails at the output side:
1. Single zener diode at one of the rails: low cost, limited in regulation due to tolerances on Zener.
2. Zener diode and shunt regulator: better regulation for voltage rails,…

Hi,
In the bias supply design guide it states that driving a transformer with 2 secondaries is possible, but stipulates that the regulation is not as good as .
My question is this…
Hi Van,
Currently we only have a Simplis model for UCC25800. I see plenty of references on the web for importing Spice models into Simplis but no Info for importing Simplis models into SPICE. I would suggest you work with application support groups inside…
