Backlight Drivers (WLED)

Easy to Use
Leveraging proprietary
assembly &
packaging technology
Leading Power Density
Reduces space requirements

Less Design Work
High integration
simplifies designs

The trend in automotive infotainment screens and digital instrument clusters is bigger and brighter. MPS offers a full range of WLED backlight drivers that can power screens from small to large, with accurate current matching and flexible dimming modes.
