PT4115 General Description

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.

What comes next is about the features. (1)simple low parts count; (2)wide input voltage range: 8V to 30V; (3)up to 12A output current; (4)single pin on/off and brightness control; (5)using DC voltage or PWM; (6)up to 1MHz switching frequency; (7)typical 5% output current accuracy; (8)inherent open-circuit LED protection; (9)high efficiency (up to 97%); (10)high-side current sense; (11)hysteretic control: no compensatio; (12)adjustable constant LED current.
