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.
