100W+, 98% Efficient Buck-Boost LED Driver Single Inductor RIN VIN VIN Input Current Monitor RLED TG1 BG1 Output Current Monitor RSENSE LT3791 SHORTLED BG2 OPENLED Analog Dimming TG2 PWM Dimming PWMOUT GND 4.7VIN to 60VIN, Short Circuit Proof with LED Protection & Diagnostics Here’s the latest in our growing family of high power, high performance LED drivers designed to simplify power delivery to high ® brightness LEDs. The LT 3791’s 4-switch buck-boost controller topology operates from input voltages above, below or equal to the output voltage while delivering constant currents from 1A up to tens of amps. The LT3791 also provides ±4% LED current accuracy and ±1.5% output voltage accuracy to ensure the highest performance LED solutions. LED Drivers Part Number VIN Range (V) Topology Comments LT3741 6 to 36 Synchronous Step-Down LED Current up to 20A LT3743 6 to 36 Synchronous Step-Down LED Current up to 40A with Fast LED Current Transitions LT3755 4.5 to 40 Multitopology VOUT up to 75V LT3756 6 to 100 Multitopology VOUT up to 100V LT3791 4.7 to 60 4-Switch Synchronous Buck-Boost VOUT from 0V to 60V with Current Monitoring Info & Free Samples www.linear.com/products/LEDdrivers 1-800-4-LINEAR , LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
