to a novel control method, the device is able to precisely regulate a
constant LED current from the primary side. This removes the need
for secondary side feedback circuitry, biasing and an optocoupler.

components. A robust suite of safety protection is built in to simplify
the design. This device is specifically intended for very compact space
efficient designs. It supports step dimming by monitoring the AC line
and detecting when the line has been toggled on−off−on by the user to
