ON Semiconductor has launched a new power factor corrected dimmable LED driver for residential and commercial lighting applications. Housed in a compact 8-pin SMT package, the NCL30000 achieves a high power factor (>0,95) in a single-stage topology by using a critical conduction mode (CrM) flyback architecture, thereby eliminating the need for a DC-DC conversion stage. Constant on-time CrM operation is particularly suited to isolated flyback LED applications, as the control scheme is straightforward and very high efficiency can be achieved, even at low power levels. Typical applications include LED driver power supplies, LED-based down lights, TRIAC dimmable LED-based lamps and power factor corrected constant voltage supplies. This device is compatible with both leading edge TRIAC-based and trailing edge transistor-based dimmers. Depending on the dimmer used, the LED output can be controlled to within 2%.

As soon as electronics and electrical systems started interfering with each other, the world had to come to some consensus. Considering physics is universal and does not care about what country electrical/electronic products are used in, it should be the same everywhere, right? It is nearly there, but not quite.
