The Atmel mSilica MSL1060 is a 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.
