The SC617 is a high-current charge pump specifically designed 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 SC617 has two modes of operation: flash mode and spotlight mode. In flash mode, the SC617 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 indefi nitely and overheat. In spotlight mode the SC617 outputs 30% of the flash current.
The SC617 is a high-current charge pump designed specifically for use with white LEDs used in camera flash applications. It features two selectable modes: Flash mode, which delivers up to 700mA output with a safety timer shut-off of 1 second, and Spotlight mode, which outputs up to 210mA continuously at 30% of the flash current.
The device includes short-circuit, over-voltage, and over-temperature protection along with soft-start functionality. It operates from an input voltage range of 3.0V to 5.25V and is available in an ultra-thin MLPD-UT-10 package measuring 3 x 3 mm.
