The SC615A is a high-current charge pump designed specifically for use with white LEDs used in camera flash applications. Only two small bucket capacitors are required to develop the output drive, providing a low EMI solution compared to inductive boost regulators. The SC615A has two modes of operation: Flash mode and 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 the LED to set the current. In Flash mode, this resistor can dissipate up to 175mW, reducing the power dissipation requirement of the SC615A. The flash input (FLASH) overrides the control input (CTRL) to make sure the flash function is activated when called for.
