Non-isolated Buck LED Driver Features? Built-in 600V power MOSFET? Without auxiliary coil power? SOP8 (DIP8) package, the output current can be up to 150mA (200mA)? SOP8 (DIP8) package, output up to 10w (18w)? Bottom switch, ? high efficiency, low EMI PF sense of volume can be adjusted to 0.9 automatically compensates for changes automatically adapt to the output inductor voltage change temperature protection Short circuit protection Overvoltage protection open fewer external components Operating temperature:???????? -40 to 100 ℃ Overview R9126 is a dedicated non-isolated step-down constant current LED driver IC, the system works in the bottom of the switch mode, high conversion efficiency, EMI low, PF can be adjusted to 0.9, the output current is automatically adapted to sense the amount of change in inductance and output voltage changes, thus truly constant current drive LED. R9126 integrated 600V power MOSFET, using SOP8 (DIP8) package, the output of up to 150 (200) mA current, the external device requires only a few can achieve excellent constant current output. R9126 integrates a rich protection features include overvoltage protection, short circuit protection, cycle-by-cycle current protection, thermal protection and soft start. R9126 has a very low start-up current and operating current, may be in the full voltage AC input (85VAC ~ 265VAC) range of highly efficient drive the LED. Applications LED drive power
