SGM3727 High Efficiency, 38V Step-Up WLED Driver GENERAL DESCRIPTION The SGM3727 is a step-up DC/DC converter designed for driving the white LEDs with an externally programmable constant current. This device features integrated, 38V power MOSFET that is capable of driving up to 10 white LEDs in series, providing inherent current matching for uniform brightness. WLED brightness adjustment is easily achieved via a single wire interface, totally 32 brightness levels of LED Dimming. The SGM3727 features a variety of protection circuits, including integrated over-voltage protection (OVP), soft-start, cycle-by-cycle current limiting, and thermal shutdown protection circuitry. FEATURES ● High-Efficiency Boost DC/DC WLED Bias Supply ● Internal 38V, 0.5Ω Power MOSFET ● Up to 10 Serial White LEDs per String ● Switch Current Limit: 1A ● Single Wire Interface 32 Brightness Levels for LED Dimming ● Programmable OVP Voltage ● Soft-Start Function ● No Leakage from VIN to GND throu.
