Efficient, Step-down, High-power LED Driver with Strobe and Synchronization for Fire Alarms (PMP9762)

This TI Design demonstrates an efficient, step-down, high-power LED driver with strobe & synchronization for fire alarms. A 3-A LED is driven from a common, quasi-regulated 12-V input bus at over 85% efficiency. The circuit supports a clock input for the strobe function, which allows synchronization of multiple LED drivers to a common clock source. As seen at APEC
