Semtech SC615

Charge Pump LED Driver for 500mA Flash (20% Torch) + Logic Interface

The SC615 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.

Features


  • 500mA Output Current - Flash Mode
  • 3.0V to 5.25V Input Range
  • Two Selectable Modes - Flash and Spotlight
  • External Flash Control Pin for Synchronization to a Camera Module or Graphics Controller
  • Spotlight Mode Current Setting - 100mA
  • Short Circuit, Over-Voltage, and Over-Temperature Protection
  • Soft-Start Functionality
  • Two Control Inputs for Maximum Versatility
  • Shutdown Current < 2µA
  • Micro Lead-frame Package MLPD-10, 3mm x 3mm
