The PT4115 is a continuous conduction mode inductive step-down converter, designed for driving single or multiple series connected LED efficiently from a voltage source higher than the total LED chain voltage. The PT4115 operates from an input supply between 6V and 30V and provides an externally adjustable output current of up to 1.2A. Depending upon the supply voltage and external components, the PT4115 can provide more than 30 watts of output power. The applications of the PT4115 include Low voltage halogen replacement LEDs, Automotive lighting, Low voltage industrial lighting, LED back-up lighting, Illuminated signs, SELV lighting, LCD TV backlighting.
