SC605
SC605 is Charge Pump Flash LED Driver manufactured by SEMTECH.
POWER MANAGEMENT Description
The SC605 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 pared to inductive boost regulators. The SC605 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. An external resistor is connected in series with the LED to set the current. In...
