Part Number: UCC28634 Other Parts Discussed in Thread: UCC28070 Tool/software: Dear Sir /madam,
we need to convert from 230V AC to 230V/15A DC (at DC_Vout)
can you suggest reference power factor correction , and also can you help as to validate attached…
Part Number: UCC28634 Hello all,
I am an undergrad electrical engineering student at Michigan Tech. I am planning on creating an AC-DC SMPS using the reference designs, calculator, and documentation provided with UCC2853X.
Since the whole circuit uses…
Part Number: UCC28634 Other Parts Discussed in Thread: UCC28610 , UCC28740 , LM5023 , UCC28600 Hi,
We already use a circuit with primary side controll for USB power. Now we wish to upgrade to proper high power USB Power Delivery protocols but the PD ICs…
Part Number: UCC28634 I received the design from the TI Webench and laid out the circuit on a PCB. When i built up the board I was not seeing the DRV switching. I troubleshot this for a while and decided to build up a second PCB with minimal components…
Part Number: UCC28634 Good morning sirs,
I am developing a Flyback using your component but although I followed the manual recommendations the resulting circuit is not delivering it's power.
It just enter in a infinite cycle of auto reset, with…
Part Number: UCC28634 Other Parts Discussed in Thread: LM5021 , Hi all, I and my friend trying to build Flyback Converter for a school project. We are getting lost because we are both software engineers however we need to pass this course to get our bachelor…
Hi Daniel,
Thank you for sending the waveforms.
I was trying to take a step back to verify your schematic which you had shared. Seeing your current parameters of Lpri-526uH and Rcs of 470mohm seems to obey the design constraints for Np=57, Ns=7, Na=8…

Basic device not working properly.
The project was conceived by the Webench power design tool and I am not able to get it to start working correctly.
As it has several fault protections I'm having a lot of difficulty in diagnosing…
Part Number: UCC28634 Hi , I am using UCC28634DR on a PCB Design for a fly back converter, designed by WEBENCH Power designer. After the fabrication and assemble of the pcb, when power was applied to the input of the circuit, the circuit did not output…
Part Number: UCC28634 Hello , I am using UCC28634DR on a PCB Design for a fly back converter , the schematic for my PCB is attached Below ,After the fabrication when I connected the input voltage to the PCB , the 200 mOhm shunt resistor exploded. Tried…
