SGM3720 Overview
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 ponents and optimized for pact 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...
