Non-isolated Buck LED Driver Features? Built-in 600V power MOSFET? DIP-8 package, the output current can be up to 350mA? Bottom switch, high efficiency, low EMI? PF can be adjusted to 0.9? Automatic compensation transformer inductance change? Automatically adapt output ? Short circuit protection temperature change in voltage overvoltage protection circuit protection fewer external components operating temperature:????? -40 ~ 100 ℃ Overview R8103 is a dedicated non-isolated buck LED controller, the system works in the bottom of the switch mode high efficiency, EMI low, PF can be adjusted to 0.9; transformer output current is automatically adapted to sense the output voltage variation and change in order to realize the constant current drive LED. R8103 integrated 600V power MOSFET, using DIP-8 package, the output currents up to 350mA, the external device requires only a few can achieve excellent constant current output. R8103 integrates a rich protection features include overvoltage protection, short circuit protection, cycle-by-cycle current protection, thermal protection and soft start. R8103 has a very low start-up current and operating current, may be in the full voltage AC input (85VAC ~ 265VAC) or 8 to 450V DC input voltage efficiently drive the LED. Applications LED drive power
