Charge Pump  
Flash LED Driver  
POWER MANAGEMENT  
Description  
Features  
The SC615 is a high-current charge pump designed spe- ‹ 500mA Output Current - Flash Mode  
cifically for use with white LEDs used in camera flash ‹ 3.0V to 5.25V Input Range  
applications. Only two small bucket capacitors are re- ‹ Two Selectable Modes - Flash and Spotlight  
quired to develop the output drive, providing a low EMI ‹ External Flash Control Pin for Synchronization to a  
solution compared to inductive boost regulators.  
Camera Module or Graphics Controller  
‹ Spotlight Mode Current Setting - 100mA  
The SC615 has two modes of operation: Flash mode ‹ Short Circuit, Over-Voltage, and Over-Temperature  
and Spotlight mode. The SC615 is capable of delivering Protection  
500mA of peak current for a duration of 500ms in Flash ‹ Soft-Start Functionality  
mode. In Spotlight mode the SC615 outputs 100mA ‹ Two Control Inputs for Maximum Versatility  
and can remain enabled continuously.  
‹ Shutdown Current < 2µA  
‹ Micro Lead-frame Package MLPD-10, 3mm x 3mm  
A minimum 0.5sense resistor is used to set the cur-  
rent through the LED in both modes. This resistor dissi-  
pates up to 0.125W, reducing the power dissipation re-  
quirement of the SC615. The flash input (FLASH) over-  
rides the control input (CTRL) to make sure the flash func-  
tion is activated when called for.  
Applications  
‹ Mobile Camera Phones  
‹ Digital Cameras  
‹ PDAs with Built-in Cameras  
‹ Multi-LED Backlit LCDs  
The thermally efficient MLPD-10 package and ceramic  
bypass and bucket capacitors help make the SC615 a  
high output current driver that requires a minimal amount  
of PCB area.
