***ment14 APAC: LT1942EUF : Quad Converter For TFT Supply and LED Driver, Vin=3V-4.5V, Von=10V/2mA, Voff=-10V/2mA, AVdd=5V/40mA

***ark: Demo Board, Lt1942 Step Up Led Driver; Device Topology:boost (Step Up); No. Of Outputs:4Outputs; Output Current:40Ma; Output Voltage:5V; Input Voltage Min:3V; Input Voltage Max:4.5V; Core Chip:lt1942; Dimming Control Type:- Rohs Compliant: Na

***log Devices: The LT1942 is a highly integrated quad switching regulator designed to provide all necessary power supply functions for TFT displays, including the white LED backlight driver. The TFT supply incorporates two boost and one inverting DC/DC converters. The TFT supply output voltages are independently set, unlike charge pump solutions which have many limitations. Power sequencing for the TFT supply is built into the part and is user programmable. The LED driver is a boost DC/DC converter that can be independently controlled. The LED driver has built-in dimming control for precise control of LED current. An 8:1 dimming range is achieved by adjusting the CTRL4 voltage. The user can elect to drive a single string or two strings of LEDs. An LED ballast circuit is included to precisely match the LED currents if two strings of LEDs are used. Soft-start is built into the LED driver as well as the primary TFT supply. The LT1942 is available in a low profile (0.75mm) 24-lead QFN (4mm × 4mm) package. Applications Poly-Silicon TFT Displays Amorphous Silicon TFT Displays
