1, MOJAY (MOjie) M8900 is a original side reverse strip single-stage active PFC high-precision LED constant current control chip, M8900 integrated single-stage active PFC line, can achieve higher power factors and very low total harmonic distortion, the chip can enter the quasi-resonant mode, so as to achieve higher efficiency and reduce switching loss.
2, there are National semiconductor company produced LM351LM270LM2795LM2795LM2796 about the same, look at your own preferences for person.
3, DOB is to put the LED constant current Driver source driver on the aluminum substrate, this technology has been available as early as 5 years ago, of course, at that time not called DOB and called light engine. The two names are very different, DOB said is a method or practice, is to put the drive power on the aluminum substrate, and the light engine is a new product name, all LED aluminum substrate with constant current drive source is called the light engine.
4LED drivers are determined according to different W numbers, and now there are a lot of driver schemes, and some different driver ics will be limited according to customer requirements.
5, MOJAY M8914 is a single stage Buck PFC controller, mainly for LED lighting applications. Higher efficiency is achieved by using a quasi-resonant mode to drive the Buck converter. Keep the Buck converter operating for a constant time to achieve a high PFC.
