SGM3760/SGM3760A 40V High Efficiency Step-Up, Dual-Channel WLED Drivers with Flash Mode GENERAL DESCRIPTION The SGM3760 and SGM3760A are dual-channel screen flash WLED drivers which provide highly integrated solutions for single-cell Li-Ion battery powered smart phone backlight. The SGM3760/A have a built-in high efficiency boost regulator with integrated 3.6A/40V power MOSFET and support as low as 2.7V input voltage. With two high current-matching capability current sink regulators, the devices can drive up to 10S2P WLEDs. The SGM3760/A are quite suitable for smart phone image capture using display device as screen flash light sources, as they can output up to 80mA/60mA current per channel at 32V for 330ms when the strobe signal is active.
