LT3743 High Current Synchronous Step-Down LED Driver with Three-State Control FEATURES DESCRIPTION n PWM Dimming Provides Up to 3000:1 Dimming Ratio The LT 3743 is a fixed frequency synchronous step-down n CTRL SEL Dimming Provides Up to 3000:1 Dimming DC/DC controller designed to drive high current LEDs. The Ratio Between Any Current average current mode controller will maintain inductor n Three-State Current Control for Color Mixing current regulation over a wide output voltage range of 0V n 6% Current Regulation Accuracy to (V 2V). LED dimming is achieved through analog IN n 6V to 36V Input Voltage Range dimming on the CTRL L, CTRL H and CTRL T pins and n Average Current Mode Control with PWM dimming on the PWM and CTRL SEL pins. n 2s Maximum Recovery Time Between Any Current Through the use of externally switched load capacitors, Regulation State the LT3743 is capable of changing regulated LED current n <1A Shutdown Current levels within several s, providing accurate, high speed n Output Voltage Regulation and Open-LED Protection PWM dimming between two current levels. The switching n Thermally Enhanced 4mm 5mm QFN and frequency is programmable from 200kHz to 1MHz through 28-Pin FE Package an external resistor on the RT pin. Additional features include voltage regulation and overvolt- age protection set with a voltage divider from the output APPLICATIONS to the FB pin.
