Semtech SC606

Charge Pump LED Driver for 6BL + Limited I2C Interface

The SC606 is a very high efficiency charge pump white/color LED driver from the mAhXLife™ family of products. It is optimized for Li-Ion battery applications. The LED current is regulated to a value configured by the user through an I2C compatible serial interface.

Features


  • Very high efficiency over 90% of battery life
  • Current regulation for 6 LEDs
  • Current matching tolerance of ± 3.5% from LED to LED
  • Current is accurate to ± 6.5% of the specified value
  • Wide current range per LED [0.5mA - 32mA]
  • High available total LED current = 6*ILED = 120 mA
  • I2C bus limited compatibility
  • Low shutdown current: 0.1 µA typical
  • Soft start / inrush current limiting
  • Short-circuit / thermal protection
  • 1.33 MHz and 250 kHz programmable fixed frequency
  • Separate brightness zones for multiple displays
  • Three charge pump modes of operation: 1x, 1.5x and 2x
  • Open LED output protection
  • MLP-16 [4x4] package
