Description

This is Infineon 320 W high-power (HP) LED driver with four channels of constant current (CC) output. This four-channel LED driver is composed of the ICL5102 320 W constant voltage (CV) reference board and four ILD8150 high-side DC-DC buck reference boards. And this is intended for anyone wishing to design HP AC-DC converters with more output channels for LED lighting.

Features

  • Dual-stage half-bridge (LLC) and separated power factor correction (PFC) with high-precision secondary side-controlled CV output.
  • Excellent output voltage accuracy of typically +/-4 percent across universal input voltage range (90 to 305 VAC) and wide output current range (from 0 to 4.35 A).
  • High PF (greater than 0.9) across universal input voltage range (90 to 305 V AC) and down to 50 percent of nominal load.
  • Low input current total harmonic distortion (iTHD less than 15 percent) across universal input voltage range (90 to 305 V AC) and down to 30 percent of nominal load.
  • Low bill of materials (BOM).

Typical applications

  • LED lighting
