The SC619 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 SC619 has two modes of operation: flash mode and spotlight mode. In flash mode, the SC619 is capable of delivering 500mA of regulated current for a duration of 500ms or up to 700mA for a reduced duration. A safety timer is also included to ensure the LED cannot be left on indefinitely and overheat. In spotlight mode the SC619 outputs 20% of the flash mode current and can remain enabled continuously. |
