PT4115

The PT4115 is a kind of continuous conduction mode inductive step-down converter which is designed for driving single or multiple series connected LED efficiently from a voltage source higher than the total LED chain voltage. The device includes the power switch and a high-side output current sensing circuit. Besides, it is available in SOT89-5 packages. The typical applications include low voltage halogen replacement LEDs, automotive lighting, low voltage industrial lighting, LED back-up lighting, illuminated signs, SELV lighting and LCD TV backlighting.
