NCL30083ADMR2G (ON SEMICONDUCTOR)
Драйвер светодиода, 1 выход, постоянный ток, 16В-20В (Vin), 150кГц, 300В/3A, µSMD-8
The NCL30083ADMR2G is a step dimmable Quasi-resonant primary side Current-mode Controller for LED lighting with thermal fold-back. This device is able to precisely regulate a constant LED current from the primary side. This removes the need for secondary side feedback circuitry, biasing and an optocoupler. The device is highly integrated with a minimum number of external components. A robust suite of safety protection is built in to simplify the design. The device supports 5 step log dimming down to 5%. To enhance system lifetime, it has current foldback at a user programmable temperature point. While this has integrated fixed overvoltage protection, the designer has the option to program a lower overvoltage protection level.
