38V High Efficiency, Boost White LED Driver with PWM Dimming Control

Preview Image
Preview Image

The SGM3736 is a high efficiency constant current LED driver with a 1.1MHz PWM boost converter. An internal low-side N-channel MOSFET and a high switching frequency make the SGM3736 easy to use small components and optimized for compact solutions.

The SGM3736 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. The LED current can be programmed by digital PWM dimming interface. The PWM frequency is in the range from 2kHz to 60kHz.

The SGM3736 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 SGM3736 is available in a Green TDFN-2×2-8L package. It operates over an ambient temperature range of -40 to +85.
