SGM3725

The SGM3725 is a high efficiency constant current LED driver with a 1.1MHz PWM boost converter. The internal low-side N-channel MOSFET and high switching frequency make the SGM3725 easy to use small components and optimized for compact solutions.

The SGM3725 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 SGM3725 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 SGM3725 is available in a Green TSOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.
