Semtech SC605

Charge Pump LED Driver for 700mA Flash (20/30/40% Torch) + Logic Interface

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.

Features


  • Two selectable modes - Flash and Spotlight
  • Up to 700mA output - Flash mode
  • Up to 280mA output - Spotlight mode
  • 500mA output over specified temperature and voltage ranges - Flash mode
  • Spotlight mode selectable to 20%, 30% and 40% of Flash current
  • 3.0V to 5.25V input range
  • Flash control pin for synchronization to a camera module or graphics controller
  • Short circuit, over-voltage and over-temperature protection
  • Soft-start functionality
  • Three control inputs for maximum versatility
  • Shutdown current < 2µA
  • Micro-lead package MLPD-12, 3mm x 3mm
