MAX1611 - Digitally Controlled CCFL Backlight Power Supplies

Description

The MAX1610/MAX1611 are fully integrated, highefficiency drivers for cold-cathode fluorescent lamps (CCFLs).

They operate from a 4.5V to 26V power source.

An on-board, high-switching-frequency power MOSFET reduces external component count and magnetics size.

19-1128; Rev 0; 9/96 KIT ATION EVALU E L B A AVAIL Digitally Controlled CCFL Backlight Power Supplies ____________________________Features _______________General Description The MAX1610/MAX1611 are fully integrated, highefficiency drivers for cold-cathode fluorescent lamps (CCFLs). They operate from a 4.5V to 26V power source. An on-board, high-switching-frequency power MOSFET reduces external component count and magnetics size. The MAX1610/MAX1611 protect against open or shorted lamps. The CCFL can be driven from an isolated transformer secondary winding to improve efficiency and avoid flicker at dim tube settings. Brightness is adjusted by scaling the lamp current, or by operating with a fixed lamp current and chopping the CCFL on and off at a rate faster than the eye can detect.
