-Data Sheet
* General Description
RM9001E is a high power factor linearconstant current LED driver which isapplied to drive three_stages of highvoltage LED string through the build_inMOS. Excellent EMI performance, smallvolume and long life can be achievedwithout the use of electrolytic capacitorsand magnetic components.
Each LED string can be set flexibly owingto the adaptive LED drive by stagesmechanism of RM9001E with highutilization rate of LED and total outputlumens. Through the distinctive constantcurrent control technology, it realizesthat constant current accuracy is less than±5% and output current is adjustablethrough external resistor. High powerfactor and low harmonic distortion are theparticular features.It needs a good thermal dissipation ambient when the current ofLED string becomes large.
RM9001E has over temperatureadjustment function.The reliability of thesystem is reinforced as the output currentreduce gradually when the power ofdriving is overheated so as to keep theheat dissipation beyond the acceptablevalue. The over temperature regulationpoint is 130ºC
