EMD2155

ESMT 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.
