MSL1061 Datasheet PDF

Atmel MSL1061

The MSL1061 operates with one of four I2C slave addresses selected from a single input pin (AD0), whereas the lower cost MSL1064 has one fixed I2C slave address. The MSL1061/64 is also easy to employ without using an I2C interface, dimming with an external PWM signal. The MSL1064 comes in a 5 x 5mm, 24-pin TQFN package, and the MSL1061 in a 5 x5mm, 28-pin TQFN.

GENERAL DESCRIPTION

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 small-sized inductor and output capacitors while maintaining high efficiency and low ripple voltage and noise. The boost regulator uses digital control and requires no external compensation. An I2C/SMB compatible serial interface operates up to 1MHz, giving access to internal 8-bit PWM dimming and 4-bit analog current adjustment for 12bit current control. Individual string enable and fault reporting are available. Analog dimming of LED string current is available for use with an ambient light sensor (ALS) and/or temperature management with a thermistor or IC temperature sensor.
