G5904 - Four Channel High Efficiency White LED Driver

Description

The G5904 charge pump drives up to four white LEDs with regulated constant current for uniform intensity.

By utilizing dynamic 1x/2x charge-pump modes and ultra-low-dropout current regulators, it achieves high efficiency over the 1-cell lithium battery input voltage range.

Features

  • Dynamic 1x/2x Charge Pump Switching.
  • Up to 80mA (20mA/LED) Drive Capability.
  • 90% Average Efficiency.
  • 0.5% (TYP) LED Current Matching.
  • Wide Current Range per LED [0.1mA ~ 20mA].
  • Single Wire EN/Brightness Control.
  • 2.7V to 5.5V Supply Voltage Range.
  • < 1µA Shutdown Current.
  • Output Over-voltage Protection.
  • Open/Short LED Protection.
  • Thermal Shutdown Protection.
  • TDFN2.5X2.5-10 and TQFN3X3-16 Pa.
