I'd like to design a LED driver from AC mains (230 Volt / 50Hz) and DC (160V - 260V). I'm looking for a single stage PSR PFC solution that generates 28V on the secondary side. Those 28V should supply a flexible LED string (1 - 8) LED @350mA. I'm thinking about NCL30160 to do the LED control capacitorless. On secondary side there is also a uC to supervise LED string current and voltage. Do you have an idea which IC can do the single stage PSR PFC? Best regards

We can offer the Power Factor Corrected Buck LED Driver NCL30002. The NCL30002 is a switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected LED Drivers. The device operates as a critical conduction mode (CrM) buck controller to regulate LED current at a high power factor for a specific line voltage range. Please see our technical documentations and evaluation board details on the NCL3002: Power Factor Corrected Buck LED Driver product page.

Another solution is the LV5026MC high voltage LED Driver which drives LED current up to 3 Amp with external MOSFET. Please see our technical documentations and evaluation board details on the LV5026MC: LED Driver product page.
