Good point. A quasi-resonant switching power supply takes about 10 person-months of development to get to production (according to "Power Supply Cookbook"). Multiplying by the cost of an engineer and dividing by 100 million chargers, works out to less than one cent for R&D. (Also, I expect STMicrosystems and Flextronics are doing most of the R&D.)
- dskhatri 14y agoThat's correct. In my experience, with such high volume opportunities, most semiconductor suppliers will provide their engineering expertise in doing (or supporting) not only the development but the reliability processes.
