Part Number: UCC28782 Other Parts Discussed in Thread: TPA3251 , UCC28780 , , UCC2893 , TL431 I'd like to design about Audio AMP.
We will adopt TPA3251 as classD Amp.
On the other hand , I will use UCC28780 as Power supply of TPA3251.
So would you please…
Part Number: UCC28780 Other Parts Discussed in Thread: UCC27712 I am interested in knowing if this controller can be used in AC output applications at 60 Hz. In other words, is it possible to modulate the reference voltage at 60 Hz to yield an AC waveform…

Part Number: UCC28780 Hello,
I'm designing an AC/DC power supply 115Vac@400Hz to 32Vdc and in primary side I’m facing startup issues with UCC28780RTE.
in the power on phase I get in SWS pin around 3.01V and for VDD, 1.83V, and it doesn’t allow…

Part Number: UCC28780 Hi,
I am designing an isolated DC-DC converter using UCC28780. It has some startup problems. The converter is restarting after 6 switching cycles (ULVO cycle reset). Observed that No overcurrent, Overtemperature, brownout,CS pin…
Part Number: UCC28780 Other Parts Discussed in Thread: TINA-TI Team,
is it possible to use the UCC28780 in a capacitor charging supply, similar to LT3751?
Is this controller in TINA and the new PSPICE for TI?
Thanks
Part Number: UCC28780 Other Parts Discussed in Thread: UCC24612 , LM321 We have a power supply product (input : 100~240Vac, output : 30V/2.34A) which used the design solution of TI UCC28780 + Navitas GaN MOSFET NV6115 + UCC24612, it can work well at full…
Part Number: UCC28780 Hi,
We are designing a 12V/65W power supply using UCC28780(QFN package). During testing, we observed that there are PWML pulses. Please see the below image CH1:Vdd CH2:Voltage on HVG pin CH3: Voltage on SWS pin, CH4: Reference voltage…
