CYT3004BM 两级恒功率线性LED恒流控制芯片

The CYT3004BM is a dual-channel progressive LEDlinear constant current control chip which usesconstant current control technology to precisely setthe LED current through external resistors.It integrates the input line network voltagecompensation function, which can maintain constantinput power by adjusting the output currentmagnitude through an external resistor within therated input voltage range.It has over temperature adjustment function toimprove the reliability of system. The system structureis simple, with few peripheral components and lowsolution cost.
