Atmel MSL1060AW
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 sGENERAL DESCRIPTION
