Atmel LED Driver-MSL1060

General Description

The Atmel® LED Driver-

MSL1060 is an LED driver

with integrated boost

regulator capable of driving

6 LED strings at 30mA up to

48V for lighting applications to

8W. In a typical backlighting

system it can drive up to 72

white LEDs.

The MSL1060 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, low ripple, and noise.

The MSL1060 uses a digital control loop and requires no external

components to manage the LED supply and regulate LED current up to

30mA per series LED string.

The MSL1060 is also easy to use, dimming with an external PWM signal.

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.

The MSL1060 is offered in a lead-free, halogen-free, RoHS-compliant, 5 x 5mm,

24-lead TQFN package operating over a -40°C to 85°C temperature range.

Applications
