This application report demonstrates the design and test results of an efficient, step-down, high-power LED driver for generating the strobe light used in fire alarms. The LED driver is enabled by an external synchronization signal, which allows multiple circuits to strobe at exactly the same time. Alternatively, an on-board timing circuit allows simple testing with a pre-configured strobe at a 1% duty cycle every second. The TPS62130 step-down converter is used in this application to provide a high efficiency and easily implemented dimming of a single 3-A LED from a quasi-regulated 12-V input voltage.

High-Power LED Driver Accepts Wide Input-Voltage Range - AN3532 Circuit based on a buck/boost converter controller regulates current to a white LED, despite an allowed variation of input voltage from 2.7V to 16.5V. The circuit of Figure 1 starts and operates a 1A LED from a voltage that ranges from 2.7V minimum (the end of life for three alkaline primary cells) to 16.5V maximum (the maximum voltage for 12V automobile systems). Operation over that range is stable and smooth, even with more than 1Ω of internal resistance at the power source.
