One-Wire Dimming, 38V Boost LED Driver

Preview Image
Preview Image

The SGM3735 is a high efficiency constant current LED driver with a 1MHz PWM boost converter. An internal low-side N-channel MOSFET and a high switching frequency make the SGM3735 easy to use small components and optimized for compact solutions.

The SGM3735 is capable of driving either up to 10 LEDs in series for 38V output or total 260mA current with 3 LEDs in series per string while achieving high conversion efficiency.

32-step FB reference voltage can be programmed by one-wire dimming interface. Compared to normal PWM dimming control, it can avoid audible noise and reduce inrush current.

The SGM3735 provides very low shutdown current. It also includes a comprehensive set of protection features such as over-voltage protection, cycle-by- cycle input current limit and thermal shutdown.

The SGM3735 is available in a Green TDFN-2×2-8L package. It operates over an ambient temperature range of -40 to +85.
