Typical (TYP) numbers are not verified, but do represent the most likely norm. Unless otherwise specified, conditions for typical specifications are: VIN = 3.6 V and TA = 25°C. (2) All voltages are with respect to the potential at the GND pin. (3) The ability to deliver 1.5 A of LED current is highly dependent upon the input voltage, LED voltage, ambient temperature and PCB layout. Depending upon the system conditions, it is possible that the device could hit the internal thermal shutdown or thermal scale- back value before the desired flash duration is reached. See Thermal Performance for more details. 6.5 Electrical Characteristics TA = 25°C and VIN = 3.6 V, unless otherwise specified. Minimum and maximum limits apply over the full operating ambient temperature range (–40°C ≤ TA ≤ 85°C).
