DESCRIPTION
t e Only two small bucket capacitors are rea t quired to develop the output drive, providing a low EMI a to inductive boost regulators. solution compared D . In Flash mode, the SC615A 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 SC615A outputs 40% of the Flash mode current and can 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 175mW, reducing the power dissipation requirement of the SC615A. The flash input (FLASH) overrides the control input (CTRL) to make sure the flash function is activated when called for. The thermally efficient MLPD-10 package and ceramic bypass and bucket capacitors make the SC615A a high output current driver that requires minimal PCB area. Charge Pump Flash LED Driver FEATURES
