White LED Boost Converter In Tiny Package

The AME5142 is a Boost DC/DC converter specifically designed to drive white LEDs with a constant current. The device CAN drive one to six LEDs in series from a Li- lon cell. Series connection of the LEDs provides identi- cal LED currents resulting in uniform brightness and elimi- nating the need for ballast resistors. The AME5142 switches at 1.2MHz, allowing the use of tiny external components. The input and output capacitor CAN be as small as 1 mF(or 4.7mF), saving space and cost versus alternative solutions. A low 0.15V feedback voltage mini- mizes power loss in the current setting resistor for better efficiency. The AME5142 is available in SOT-26/TSOT-26 & SOT-25/TSOT-25 packages. By AME, Inc.
