Download the SP2798B datasheet PDF. This datasheet also covers the SP2798A variant, as both devices belong to the same main line power up non-isolated buck apfc led driver family and are provided as variant models within a single manufacturer datasheet.

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.

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.
