Part Number: UCC28070-Q1 Other Parts Discussed in Thread: AMC1302 , UCC28070 , UCC3818A , UCC28060 Tool/software: Hi
I'd try the Three-Phase Semi-Bridgeless PFC Topology Using UCC28070-Q1 (Analog IC).
The principle is using the isolatedhalf sine wave…
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…
Hello Jeon,
Please refer to this previous E2E on the topic: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1077117/ucc28060-what-is-the-role-of-the-bypass-diode The bypass diode is common to all non-isolated…
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…
Hello,
There was an article written years ago that discussed semi bridgeless PFC vs interleaved PFC from power electronic technologies. You can find the article at the following link.
This article evaluated the UCC28060 CrM PFC in a semi bridgeless…
Hello,
RTESET sets the minimum switching period and maximum on time. A larger resistor would mean a larger maximum on time. I wonder if during power up you were hitting peak current limit.
When the power converter starts up both inductors are…
Hello Mike,
The UCC2851x family of combination type controllers parts are based on a boost CCM stage followed by a flyback stage. They can certainly be used for 150W LED lighting applications. The advantages of this part are that they offer very good…
Hi Dinesh,
UCC28060 might be a good fit for your design. Here is an interleaved flyback reference design for LED driver: www.ti.com/.../slua625.pdf
