The LT3743 offers both PWM and CTRL_SELECT dimming, enabling 3,000:1 dimming capability at three LED current levels, making it ideal for color mixing applications such as those required in DLP projectors. Similarly, the LT3743’s unique topology enables it to transition between two regulated LED current levels in less than 2µs, which optimizes color mixing resolution and allows fast current pulsing in laser driver applications. An LED current accuracy of ±6% is maintained in order to ensure the most accurate luminosity of light output from the LED. Additional features include output voltage regulation, open-LED protection, over current protection, and a thermal derating circuit.
