SC605 is a high-current charge pump designed specifically for use with white LEDs used in camera flash applications. It has two modes of operation: Flash mode and Spotlight mode. In Flash mode, the SC605 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 SC605 can output 20%, 30%, or 40% of the Flash mode current and remain enabled continuously.
The SC605 is a 2x charge pump specifically designed to drive high-intensity white LEDs used in camera flash applications. It operates in two modes: Flash mode and Spotlight mode. In Flash mode, it delivers up to 700mA for short durations or 500mA regulated current for up to 500ms. In Spotlight mode, it provides continuous output at 20%, 30%, or 40% of the Flash mode current.
The device features a compact MLPD-12 package and includes protection circuitry such as short-circuit, over-voltage, and over-temperature protection. It is designed to be driven by an external resistor connected in series with the LED to set the output current.
