GENERAL DEscriptION

The SGM3727 is a high efficiency current-regulated white LED driver with a boost DC/DC converter. With an internal 38V/1A power MOSFET, the SGM3727 supports up to 10 white LEDs in series and achieves uniform brightness. 32-step LED current can be set by a serial pulse signal into the EN/SET pin.

The SGM3727 includes a comprehensive set of protection features such as over-voltage protection, cycle-by-cycle current limit and thermal shutdown. Built-in soft-start circuitry avoids excessive inrush current during startup.

The SGM3727 is available in a Green TDFN-2×2-8L package. It operates over an ambient temperature range of -40℃ to +85℃.
