Part Number: UCC28064A Hello, Do you have any further readings I could use to better understand how the equations for Voltage Loop Compensation (section 9.2.2.11) are derived? I am trying to understand the logic behind Rz, Cz, and Cp selections. Thanks…
Part Number: UCC28064A Other Parts Discussed in Thread: TIDA-010015 I am looking at TIDA-010015 reference design which uses UCC28064A. In this design, two external gate drive ICs are used to drive the two MOSFETs in interleaved boost converters. Why are…
Part Number: UCC28064A Other Parts Discussed in Thread: PMP30763 , PMP31179 I cannot see any major difference between PMP31179 and PMP30763 which may affects harmonic emission greatly.
However PMP31179 much worse than PMP30763 at 800Hz DO160 Harmonic test.
C…
Part Number: UCC28064A Hello Ti,
We are designing pfc with UCC28064A and we did not realize how to select RTset value.
It seems the Rtset value, not only affect maximum frequency, but also affect minimum frequency.
Can you give me a guideline about…
Part Number: UCC28064A Other Parts Discussed in Thread: UCC256404 , On the specs page I see that this device supports systems with power less than 150W. I planned to use this part with UCC256404 LLC controller, as suggested on the datasheet of the LLC controller…
Part Number: UCC28064A Hi Power Group,
PFC input stage is running well but looking for methods to lower the 3rd current harmonic.
Fundamental current is 3.0Amp and 3rd harmonic is 150mA. My criteria calls for a limit of 160mA.
While the circuit is passing…
Part Number: UCC28064A Hi Power Group,
What parameters set the upper switch frequency of a Transitional Mode PFC or Single Stage Flyback PFC?
Normally I see switch frequencies in the 100K range. Can the PFC inductor or Flyback transformer size be reduced…
Part Number: UCC28064A Other Parts Discussed in Thread: UCC28064 , TPS92314 , UCC28060 We plan to use UCC28064A to implement a single-stage flyback PFC, while the output voltage is adjustable. However, we have encountered a problem that the voltage of the…
Part Number: UCC28064A Other Parts Discussed in Thread: UCC28060 , UCC28063A , Hi Group,
SLUA625 details LED Driver Based on UCC28060 Interleaved ACDC Single Stage Flyback.
My application is low power (25W) but limits the transformer width to 19mm. Using…
