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 compared 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 Flash mode, this resistor can dissipate up to 0.175mW, reducing the power dissipation requirement of the SC605. The Flash input (FLASH) overrides the control inputs (CTRL0 and CTRL1) to ensure the Flash function has the highest priority.

The thermally efficient MLPD-12 package and ceramic bypass and bucket capacitors help make the SC605 a high output current driver that requires a minimal amount
