Quad LED Driver Drives up to 32 1A LEDs & Offers 1000:1 True Color PWMTM Dimming

Linear Technology Corporation announces the LT3476, a 2MHz DC/DC converter designed to operate as a four channel constant current LED driver. Each channel of the LT3476 can drive up to eight 1A LEDs in series, enabling the LT3476 to drive up to 32 1A LEDs while delivering efficiencies up to 96%. Each of the four channels is operated by an independent True Color PWM signal, enabling each channel to be dimmed independently to ratios as high as 1000:1. A fixed frequency, current mode architecture ensures stable operation over a wide range of supply and output voltages.
