    LED Backlight Drivers PWM Dimming, 38V Boost LED Driver Integrated Circuit IC Chip

    LED Backlight Drivers PWM Dimming, 38V Boost LED Driver Integrated Circuit IC Chip
    The SGM3732 is a high efficiency constant current LEDdriver with a 1.1MHz PWM boost converter. An internallow-side N-channel MOSFET and a high switchingfrequency make the SGM3732 easy to use smallcomponents and optimized for compact solutions.
    The SGM3732 is capable of driving either up to 10LEDs in series for 38V output or total 260mA currentwith 3 LEDs in series per string while achieving highconversion efficiency. The LED current can beprogrammed by digital PWM dimming interface. ThePWM frequency is in the range from 2kHz to 60kHz.
    The SGM3732 provides very low shutdown current. Italso includes a comprehensive set of protectionfeatures such as over-voltage protection, cycle-bycycle input current limit and thermal shutdown.The SGM3732 is available in a Green TSOT-23-6package. It operates over an ambient temperaturerange of -40℃ to +85℃
