Liquid Crystal Display and Backlight Integrated Controller
The MC34270 and MC34271 are low power dual switching voltage regulators, specifically designed for handheld and laptop applications, to provide several regulated output voltages using a minimum of external parts. Two unmitted switching regulators feature a very low standby bias current of 5.0 µA, and an operating current of 7.0 mA capable of supplying output currents in excess of 200 mA. Both devices have three additional Features
. The first is an ELD Output that can be used to drive a backlight or a liquid crystal display. The ELD output frequency is the clock divided by 256. The second feature...
