REF_ILD8150E_HE ILD8150E high efficiency reference design with headroom voltage control

概要

The reference board REF_ILD8150E_HE shows how to enable headroom voltage control in LED drivers by combining an AC-DC flyback controller and a DC-DC buck converter, enhancing system performance and reducing design costs. 

特長

  • Input voltage up to 80Vdc
  • Up to 1.5 A output current
  • Hybrid dimming from 0.5 % to 100%
  • Digital soft-start
  • Typical ±3% output current accuracy
  • Cycle by cycle current limit
  • PG-DSO-8 package with exposed pad

利点

  • No external MOSFET needed
  • Deep dimming and flicker-free light
  • High efficiency headroom voltage control
  • Current always under control
