ML4876数据手册Micro Linear中文资料规格书

描述 Description

GENERAL DESCRIPTION
The ML4876 is an ideal solution for driving small cold cathode fluorescent tubes (CCFL) used in liquid crystal display (LCD) backlight applications. It provides the dimming ballast control and the contrast control for the LCD display.FEATURES
■ 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
