The SGM3735 is a versatile constant current LED
driver with a high efficiency step-up converter
architecture. Unique technology and high 1.35A current
limit allow SGM3735 to drive up to 38V output (10
LEDs in series). Alternatively, SGM3735 can deliver
260mA total current with 3 series LEDs per string. It
can also maximize the current capability while
achieving high conversion efficiency. The optimized
1MHz switching frequency results in reduced
conduction loss and small external component size. A
single wire dimming interface is integrated to adjust the
FB voltage in 32 steps, which can overcome audible
noise and inrush current issues in normal PWM
dimming schemes.
Various protection features are built into the SGM3735,
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. SGM3735YTDE8G/TR资料下载
