High Efficiency 6 White LED Driver With Open LED Protection

The AME5142C is a Boost DC/DC converter specifi- cally designed to drive white LEDs with a constant cur- rent. The device CAN drive 1 to 6 LEDs in series or mul- tiple strings from a Li-lon cell. Series connection of the LEDs provides identical LED currents resulting in uni- form brightness and eliminating the need for ballast re- sistors. The AME5142C switches at 1.2MHz, allowing the use of tiny external components. The input and out- put capacitor CAN be as small as 0.22mF, saving space and cost versus alternative solutions. A low feedback volt- age minimizes power loss in the current setting resistor for better efficiency. The AME5142C is available in SOT- 26/TSOT-26 packages. By AME, Inc.
