Highly Efficient 3-String White LED Driver

The SGM37603 is a high efficiency 3-string white LED driver with a 1.2MHz boost converter. The supply voltage operates from 3V to 24V. The SGM37603 is capable of driving up to 8 LEDs in series for 25mA maximum LED current per string while achieving high conversion efficiency. An adaptively current-regulated method allows different LED string voltages while LED current remains in regulation. The LED current is programmed through an I²C interface or a PWM signal input. These features make it optimized for compact solutions and ideal for LCD display backlighting.

The SGM37603 is available in Green WLCSP-1.78×1.36-12B and TDFN-3×3-12L packages. It operates over an ambient temperature range of -40℃ to +85℃.
