High efficiency 6 white LED driver with open LED protection , SOT26, AME, RoHS

The AME5142 is a Boost DC/DC converter specifically designed to drive white LEDs with a constant current. The device can drive 1 to 6 LEDs in series or multiple strings from a Li-lon cell. Series connection of the LEDs provides identical LED currents resulting in uniform brightness and eliminating the need for ballast resistors.

Features:

  • 1.2MHz Fixed Switching Frequency
  • 28V Over Voltage Protection
  • Over Temperature Protection
  • Internal Soft Start
  • 30V Internal Switch
  • Drives Up to 6 LEDs from a 2.7V Supply at 20mA
  • Only small external Capacitors and Inductor required
  • Cycle-by-Cycle Current Limiting
  • Up to 88% Efficiency
  • Meet RoHS Standards
