SC615A
SC615A is Charge Pump Flash LED Driver manufactured by SEMTECH.
m o c POWER MANAGEMENT . U 4 Description t e The SC615A is a high-current charge pump designed spee h cifically for use with white LEDs used in camera flash S applications. Only two small bucket capacitors are rea t quired to develop the output drive, providing a low EMI a to inductive boost regulators. solution pared D . w The SC615A has two modes of operation: Flash mode w and w Spotlight mode. In Flash mode, the SC615A is capable of delivering 500mA of regulated current for a duration of 500ms or up to 700mA for a reduced duration. In Spotlight mode the SC615A outputs 40% of the Flash mode current and can remain enabled continuously. An external resistor is connected in series with...
