EMD2155
Off-Line, Non-isolated Linear AC LED Driver
With Auto Power Compensation
General Description
The EMD2155 is a non-isolated linear LED driver for
general purpose LED lighting applications. It is
capable of driving LEDs in multiple series
connections and operating in multiple phases. The
EMD2155 is designed 3 steps constant current that
balance each sink paths.
The EMD2155 has built-in temperature and power
compensation mechanisms to compensate for the
temperature and line voltage variation. TriAC and
PWM dimming control circuits are available.
The EMD2155 is based on a patented architecture
that allows minimal external components to greatly
enhance the lighting system reliability and drastically
reduce system cost. Due to its non-switching
behavior, the system is never an EMI issue.
