NTE7208 Integrated Circuit Constant Current Single Output LED Driver Description: The NTE7208 is a step- down constant current source designed for driving high power white LEDs. A standard output current of 350mA makes this driver compatible with a wide range of LEDs from many different manufacturers without the need for any external components. Editor Don Tuite' s Pick for the Best Analog Announcement of is Linear Technology' s LT3092 constant current source,. and we can handle that with one IC, ” Dobkin continued. Constant Current Regulator & LED Driver 45 V, 20 mA 15%, 460 mW Package The linear constant current regulator ( CCR) is a simple, economical and robust device designed to provide a cost− effective solution for regulating current in LEDs ( similar to Constant Current Diode, CCD). The CCR is based on Self- Biased Transistor ( SBT) technology and.
