Hi Cameron,
For higher power we recommend the CCM boost topology. It is possible to use single stage PFC boost up to 1kW using the UCC28180, the interleaved approach offers a benefit in terms of reduced ripple currents on the input and output stage…
Hello KJ
Yes - the UCC29950 can control a 600W power stage but we don't have a reference design at tha tpower level.. The main thing to do is to make sure that the input current sensing signals are scaled correctly - that is the signals into the PFC_CS…
Hi KJ,
UCC29910A is Buck PFC controller and the total output power is 2.8kW, Buck PFC is not applicable for such high power application since input peak current is very high. At 2.8kW power level you should probably look at a CCM PFC. The choices are…

Hi Yokoto-san
Yes you could use only one output of these devices. I don't think there are any problems - the UCC28060 provides a PHB pin to turn GDB off. There is no internal way to disable one of the outputs of the UCC28070 but you can tie one of…
Part Number: UCC27531 Other Parts Discussed in Thread: UCC28180 , UCC28951 , UCC28950 , Hi,
I have designed PFC stage according to TIDA-00779 using UCC27531D.
I am testing the circuit without AC Input. I have connected a DC source to Vsense to simulate…
Hi SHAHRIAR MOHAMMADI,
You will need a power factor controller to provide the PFC function. The following parts should be suitable for this function:
UCC28070; UCC28064; UCC28063; UCC28180 would be suitable controllers for the PFC function.
You may…
The first page in all of TI's data sheets are meant to highlight the parts unique features and showcase the advantages over prior ic controllers.
The graph in question shows the relative reduction in capacitor ripple current between a single phase TM…
James,
A 3 phase aircraft power source has a line to line voltage of 115V. If you rectify the 3 phases with a 6 diode bridge then the input current will look like a quasi square wave with a curved top. This happens because the phase that was conducting…
hi, KK
for PFC IC, besdes UCD3138, there are UCC28180 for single phase CCM, and UCC28070A for two phases interleaved CCM PFC.
PWM IC, what topology you want to use for DC/DC stage?
regards,
yunsheng
