Part Number: UCC28513 Hi all,
We received notification UCC28513DW will be discontinud. See PDN# 20230920001.3.
Replacement being UCC2851 2 DWR.
Seems the Tube version is ending production but the Large Reel continues production: can you please…
Part Number: UCC28513 Other Parts Discussed in Thread: UCC28512 On the UCC28513 block diagram, there is a signal called CLK2 that controls a FET that discharges a capacitor. What is this capacitor value, what voltage is applied on the RT pin, and how…
Part Number: UCC28513 Other Parts Discussed in Thread: UCC3817 , UCC2817 This is a follow-up to the case no. above.
We were able to mitigate the current distortion. But, now the PFC output voltage seems unstable under certain conditions.
The attached…

Part Number: UCC28513 Other Parts Discussed in Thread: UC3854 , UC1854 Hi Experts,
Good day. Seeking your assistance on this query from a customer:
"I have a PFC boost converter design based on the data sheet of this chip. It is a 150W power supply…
Part Number: UCC28513 I am considering the use of the UCC28513 due to the success one of my colleagues has had with it. However, I'm considering using the PFC in a SEPIC configuration as that naturally solves an inrush issue I have to deal with. Certainly…
Part Number: UCC2818A Other Parts Discussed in Thread: UCC28513 , I am designing a PFC for a 400Hz application. A colleague of mine successfully designed a good PFC that drove a Flyback using the UCC28513. I am weighing my options between the 28513 and…
Hi Adrian,
We don’t have Webench model for device UCC28513 .
Currently WEBENCH supports only PFC-BOOST, combination of PFC/PWM are not enabled in WEBENCH.
Kindly revert back to us on any further queries.
Thanks and Regards,
Umayal
Part Number: UCC28513 Other Parts Discussed in Thread: UCC2818A If the PWM section of the UCC28513 is not being used, how should the unused pins be tied?
Other Parts Discussed in Thread: UCC28513 The UCC28513 datasheet selects the R2 sense resistor by setting Vdynamic to 1 V. Is there a min and max range that Vdynamic can use for proper operation of the converter? If I increase the max current by adjusting…
