Superior, energy efficient lighting for the mainstream.

SINGLE STAGE AC/DC CONSTANT CURRENT INTELLIGENT LED DRIVER IC

88EM8189

The Marvell 88EM8189 is a single-stage AC/DC constant current, intelligent LED controller featuring an integrated I2C compatible interface. The I2C interface connects to networking microcontrollers to provide digital dimming through ZigBee®, Wi-Fi, Bluetooth, PLC and other technologies. Additionally, the 88EM8189 has an energy efficient on-chip AC-DC converter for bias power supply to the networking microcontroller that enables meeting ENERGY STAR power consumption (500mW standby) in standby mode (when light is off). Used in conjunction with a network controller, the 88EM8189 is part of two-chip solution that accelerates the development of smart wireless lighting with a low cost BOM and quick time to market. Moreover, the 88EM8189 enables the smart bulbs to be backward compatible to phase cut wall dimmers, providing flick-free dimming performance. The 88EM8189 can also be used in either Buck-Boost (non-isolated) or Flyback (isolated) design topologies.
