Demonstration circuit 810 is a high efficiency buck-boost flash LED driver featuring the LTC3453 and the LXCL-PWF1 Lumileds Luxeon Flash LED. The board is optimized for 500mA (300ms) LED flash current or 150mA constant LED torch current with a single Lithium-Ion battery input voltage range of 2.7V to 4.2V or three AAA batteries in series. The Lithium-Ion battery input voltage range, high LED flash current and separate torch mode current setting, internal synchronous power switches, minimal and low-profile external components, and simple design makes the LTC3453 a great solution for highly efficient, space-constrained cellular telephone camera flash solutions. DC810 comes with three AAA batteries in series to simulate the capabilities of a typical Lithium-Ion cellular telephone battery.
