Description: LCD Backlight Lamp Driver with Contrast

Features

* s s s s s s s s Backlight lamp driver with differential drive Up to 30% lower power for same light output Low standby current (< 10µA) Improved efficiency (»95%) Allows all N-channel MOSFET drive Low switching losses Resonant threshold detection Buck regulator uses synchronous rectification BLOCK

Applications

* It provides the dimming ballast control and the contrast control for the LCD display. By utilizing differential drive the ML4876 can deliver the same light output with significantly less input power compared to existing single ended drive schemes. Improvements as high as 30% can be realized when us
