Test Report — Efficient, Step-down, High-power
LED Driver with. 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

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.
