UCC28730: One-chip solution of primary power supply (with built-in PFC) + secondary LED driver

Part Number: UCC28730

Tool/software:

Hi,

I am looking for a one-chip solution of primary power supply (with built-in PFC) + secondary LED driver. I am currently using ON Semiconductor FL7733A, but am considering UCC28730 as a new option. The LED lighting I am considering only requires constant current control, but UCC28730 seems to be a constant voltage constant current IC. Could you give me some advice based on this?

The LED lighting specifications are as follows.

- Input voltage: Compatible with both 100V/200V
- Output voltage: 12V to 55V
- Output current: 2 patterns of 700mA
- PSE, CISPR15 compliant

Thanks,

Conor
