General Description
RLD1301 is a LED driver IC for direct AC powered
LEDs. Inductor and electrolyte capacitors are not
necessary implementing a driving circuit. Thus the lifetime
of LED lamps can be extended up to LED chips itself. The
output current level is adjustable via an external resistor.
Dimming control can be accomplished with current control
circuit or TRIAC phase control switch. The NTC (Negative
Temperature Coefficient) characteristics of the control
block ensure stable operation of LED lamps under over
voltage and over temperature. THD (Total Harmonic
Distortion) can be reduced to below 20%, and PF (Power
Factor) is close to 1. RLD1301 offers the competitive
solution for AC direct drive LED lamps with a robust long
lifetime and cost effectiveness.
