2 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.
