SGM3747 PWM Dimming, 38V Step-Up LED Driver GENERAL DESCRIPTION The SGM3747 is a versatile constant current LED driver with a high efficiency step-up converter architecture. The low-side power MOSFET is integrated in the device, significantly shrinking the overall PCB layout area and minimizing the total number of external components. Unique technology and high 1.6A current limit allow SGM3747 to drive up to 38V output (10 LEDs in series). Alternatively, SGM3747 can deliver 260mA total current with 3 series LEDs per string. It can also maximize the current capability while achieving high conversion efficiency. The optimized 1.1MHz switching frequency results in reduced conduction loss and small external component size. Digital PWM dimming interface is integrated to adjust LED current.
