General Description

The SP2788Xare built-in HV start-up and IC power supply circuit, main line power up constant current LED regulators with high current accuracy which applies to single stage step-down power factor corrected LED drivers.

600V power MOSFET is integrated, which can significantly simplify the design of LED lighting system.

High accuracy of output current is achieved by sampling the output current directly.

Key Features

  • Active PFC for High power factor and low THD.
  • Built-in HV start-up and IC power supply circuit, The VDD power supply resistors and power feedback circuits from LED chips are not needed.
  • 600V high voltage MOSFET integrated.
  • ±3% LED output current accuracy.
  • Excellent line and load regulation.
  • Quasi-Resonant (QR) Buck topology.
  • System efficiency up to 95%.
  • Ultra low start up & operating current.
  • Cycle-by-cycle cur.
