SGM3732 Datasheet | SG Micro

DESCRIPTION The SGM3732 is a versatile constant current LED driver with a high efficiency step-up converter architecture. The low-side power MOSFET is integrated in the device, significantly shrinking the overall PCB layout area and minimizing the total number of external ponents. Unique technology and high 1.35A current limit allow SGM3732 to drive up to 38V output (10 LEDs in series). Alternatively, SGM3732 can deliver 260m A total current with 3 series LEDs per string. It can also maximize the current capability while achieving high conversion efficiency. The optimized 1.1MHz switching frequency results in reduced conduction loss and small external ponent size. Digital PWM dimming interface is integrated to adjust LED current. The PWM frequency is in the range from 2k Hz to 60k Hz. Various protection features are built into the SGM3732, including cycle-by-cycle input current limit protection, open LED (output over-voltage) protection and thermal shutdown protection. The leakage current in shutdown mode is less than 1µA. The SGM3732 is available in a Green TSOT-23-6 package. It operates over an ambient temperature range of -40℃ to +85℃.
