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 0.5Ω sense 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.
