SGM3759 Datasheet Boost WLED Driver

Manufacturer: SG Micro

Datasheet Details

With a 40V rated integrated switch FET, the SGM3759 is a boost converter that drives LEDs in series.

The boost converter has a 40V, 3A internal MOSFET;

thus it can drive single or parallel LED strings for small to large size panel backlighting.

SGM3759 38V High Efficiency, Boost WLED Driver with Strobe Interface for Flash Mode.

integrated open LED protection that disables the SGM3759 to prevent the output voltage from exceeding the IC absolute maximum voltage ratings during open LED conditions. When the device is working, if the STROBE pin is pulled up, it will turn on flash mode within 100µs. And the feedback voltage is regulated to 5× of the backlight mode that determined by the PWM signal duty cycle. And it will turn to backlight mode within 100µs when the STROBE pin is pulled down or the strobe signal keeps high ov.
