SGM3743 Part Attribute
- Description The SGM3743 is dual-channel WLED driver which provides highly integrated solutions for single-cell Li-ion battery powered smart phone backlight. The device has a built-in high efficiency boost regulator with integrated 1.5A/40V power MOSFET and supports as low as 3V input voltage. With two high current-matching capability current sink regulators, the device can drive up to 10S2P WLED diodes. The boost output can automatically adjust to the WLED forward voltage and allow very low voltage headroom control, thus to improve LED strings efficiency effectively. The SGM3743 support both of the PWM dimming interface and one wire digital dimming interface and can realize 9-bit brightness code programming. The SGM3743 integrates built-in soft-start, over-voltage, over-current protection, and thermal shutdown protection. The SGM3743 is available in a Green WLCSP -1.32×1.32-9B package and operates over the -40℃ to +85℃ temperature range.
