Device Design Dept. (Joined the company in 1991) 1 Introduction Development of the MR2000 Series Energy conservation guidelines from the Ministry of Economy, Trade and Industry require a reduction in the standby power consumption of various types of electrical products as a means of reducing environmental CO 2 levels. There are strong demands for reduced power consumption in common devices such as TVs and set top boxes (STB) which remain on standby for long periods of time, and efficient operation under micro-loads is required. Furthermore, demands for integration of the various protective functions, higher functionality, and lower price are increasing to the extent that it is now difficult to satisfy such demands with existing products. www.DataSheet4U.com In response, a Multi Chip Module (MCM) structure, incorporating only a main switch and control IC, has been adopted in the development of the MR2000 Series of highly functional and low-cost IC modules. 2 Outline The MR2000 Series includes the 100V input and 200V/worldwide input IC modules, with a function for burst mode switching under micro-load. The 100V input MR2500 Series employs a 500V resistant MOSFET, while the 200V/worldwide input MR2900 Series employs a newly developed 900V resistant high-speed IGBT and a switching de...
