The four-channel reference design features a dual-stage half-bridge LLC and separated PFC stage, providing high-precision constant voltage output with deep dimming and flicker-free light on the secondary side. It offers significant cost savings, scalability, and low input current total harmonic distortion (iTHD less than 15%) across a universal input voltage range.

Features

  • 320W high-power design
  • High performance LLC design
  • Up to 1.5A average output current per channel
  • PWM dimming input with 250Hz to 20kHz PWM dimming frequency
  • Analog dimming 100 to 12.5%
    PWM dimming 12.5 to 0.5% with 3.4kHz flicker-free modulation

Benefits

  • Ready to go AC-DC and DC-DC solution with four channels
  • High efficiency
  • High light quality
  • Balanced BOM performance
