RFT1150 Product details

Description

Pin Assignment RFT1150 is a multi-output constant current LED driver.With its linear architecture, the external circuits can be significantly simplified to 4 external resistors for adjusting the RGBW (or amber) output current.RFT1150 provides a maximum sink current of 350 mA for each channel, with a reasonable value of the external resistor.The output pin of RFT1150 endures a maximum voltage of 17 V, allows more series power LEDs in a string.Besides, users can perform dimming control throu
