BCT3756 High Efficiency, Support 0.3% PWM Dimming Boost WLED Driver BCT3756 High Efficiency, Support 0.3% PWM Dimming Boost WLED Driver GENERAL DESCRIPTION The BCT3756 is a white LED driver with integrated boost converter. With an internal 38V switch FET, the BCT3756 drives up a string of up to 10 LEDs in series. The boost converter runs at 1.1MHz fixed switching frequency to reduce output ripple, improve conversion efficiency, and allows for the use of small external components. The default white LED current is set with the external sense resistor RSET, and the feedback voltage is regulated to 200mV, as shown in the typical application.
