nn PWM Dimming Provides Up to 3000:1 Dimming Ratio nn CTRL_SEL Dimming Provides Up to 3000:1 Dimming Ratio Between Any Current nn Three-State Current Control for Color Mixing nn ±6% Current Regulation Accuracy nn 6V to 36V Input Voltage Range nn Average Current Mode Control nn 2µs Maximum Recovery Time Between Any Current Regulation State nn <1µA Shutdown Current nn Output Voltage Regulation and Open-LED Protection nn Thermally Enhanced 4mm × 5mm QFN and 28-Pin FE Package APPLICATIONS nn DLP Projectors nn High Power Architectural Lighting nn Laser Diodes The LT®3743 is a fixed frequency synchronous step-down DC/DC controller designed to drive high current LEDs.
The average current mode controller will maintain inductor current regulation over a wide output voltage range of 0V to (VIN – 2V).
LED dimming is achieved through analog dimming on the CTRL_L, CTRL_H and CTRL_T pins and with PWM dimming on the PWM and CTRL_SEL pins.
