38V High Efficiency, Boost White LED Driver with PWM Dimming Control
The SGM3720 is a high efficiency constant current LED driver with a 600kHz PWM boost converter. The internal low-side N-channel MOSFET and 600kHz switching frequency make the SGM3720 easy to use small components and optimized for compact solutions.
The SGM3720 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 SGM3720 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 SGM3720 is available in a Green TSOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.
