ON Semiconductor's NCL30030 PWM controller. This device integrates a power factor correction (PFC) and a quasi-resonant flyback controller to ensure a compact, efficient A / -DC LED driver for high-performance, low-ripple LED lighting applications. The quasi-resonant current mode flyback stage has a proprietary valley lock circuit to ensure stable valley switching and work before falling to the fourth valley, then switch to frequency foldback mode and clamp at the minimum frequency Exceed the 4th trough. Eliminate noise. The PFC stage has a proprietary multiplier architecture that achieves low harmonic distortion and close to unity power factor when operating in critical conduction mode (CrM). NCL30030 also has skip mode operation, which can achieve high efficiency under light load conditions, but the power consumption is very low, which is very important in SMART lighting applications. Other features of the NCL30030 include boost diode short-circuit protection, adjustable PFC disable threshold, 700V rated high-voltage start-up circuit and timer-based overload protection. Typical applications include AC / DC low-ripple LED drivers, LED electronic control gears, LED driver power supplies, and LED sign power supplies. This controller is ideal for LED luminaires, medical and industrial power supplies below 250W, and open-type power supplies and adapters below 250W.
