The SC615 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 SC615 has two modes of operation: Flash mode and Spotlight mode. The SC615 is capable of delivering 500mA of peak current for a duration of 500ms in Flash mode. In Spotlight mode the SC615 outputs 100mA and can remain enabled continuously. A minimum 0.5 sense resistor is used to set the current through the LED in both modes. This resistor dissipates up to 0.125W, reducing the power dissipation requirement of the SC615. The flash input (FLASH) overrides the control input (CTRL) to make sure the flash function is activated when called for. |
