RLD1203 Linear Type LED Drive IC Features l l l l Package Type : P-6020G Current source for LED lamp Adjustable constant current up to 400mA Suitable for high LED lamp Negative temperature coefficient Heat Sink 2 1 Applications l l MR16 type LED lamp Universal constant current source 3 4 5 General Description RLD1203 is a LED drive IC for driving LED lamp of operating current ranges from 100mA up to 400mA. The output current level is adjustable via an external current adjust resistor. The NTC (Negative Temperature Coefficient) characteristic of the control block ensures stable operation of LED lamps under over voltage and over temperature. RLD1203 offers the competitive solution for drive LED lamps with a robust long lifetime and cost effectiveness.
