General Description
The CRD1631-10W reference design demonstrates the
performance of the CS1631 resonant mode AC/DC
dimmable LED driver IC with constant current output
driving 483mA for white LEDs and 185mA for red LEDs in
series 2 channel output configuration. It offers best-in-class
dimmer compatibility with leading-edge, trailing-edge, and
digital dimmers. Additionally, it offers superior 2 channel
control with single channel LED temperature compensation
for LED color mixing applications. The form factor is
targeted to fit into many LED bulb applications (A19, PAR).
