MSL1064 Overview
The Atmel® LED DriversMSL1061 and MSL1064 are LED drivers with integrated boost regulators capable of driving six LED strings at 30mA up to 48V for lighting applications to 8W, allowing up to 72 LEDs per driver backlighting applications. The MSL1061/64 incorporates a current mode PWM boost regulator with 50V internal switch and a wide, 4.75V to 36V input voltage range. The 1.1MHz switching frequency uses a...
