tw 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 through the individual output enable signals for RGBW lighting.
Features  Operating supply voltage: 3.
3 V ~ 5 V  Constant current output: 20 mA ~ 350 mA (VDD = 5 V)  Max.
output voltage: 17 V  Max.
output enable frequency: 1 MHz  Accurate output current adjustment through individual external resistors  Thermal protection (auto current reduction High/low threshold: 180 °C & 120 °C)  Thermal alarm ( over 140 °C)  LED open detection Application High brightness LED lighting Architectural or entertainment LED lighting Pin Pin No.
