88EM8803

88EM8803

The 88EM8803 is Marvell’s second generation chip based on the industry's first intelligent DC/DC two-channel LED controller 88EM8801. This intelligent dual-string Pulse-Width Modulation (PWM), dimming LED driver based on DC/DC Buck topology uses high levels of integration and mixed signal technology. It also includes an I2C compatible digital interface integration for wireless lighting control connection with a variety of network microcontrollers such as ZigBee, PLC, Wi-Fi, and Bluetooth for dimming and on/off control. In addition to reducing the size, design complexity and cost of LED power electronics, the intelligence of the 88EM8803 chip significantly enhances light quality while reducing LED component expenses.

Features

  • Dual-string high-efficiency LED driver with synchronous buck topology
  • Up to 60V output voltage, 1,000 mA LED output current for first string and second string
  • Up t0 60 input voltage
  • Selectable buck switching frequency, within 200kHz and 800kHz range
  • Flexible OTP memory configuration capability for compensating the die-to-die output variation
  • Dual channel DC/DC synchronous buck converter with integrated low-side switch
