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

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.

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.

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 device optimized for the various input ranges.

Both devices are partial resonance power supply IC modules comprising a low power consumption

control IC as the control circuit.

MR2000 Series modules are contained in a fully molded MA Series package as used for previous

power supply hybrid ICs with an added screw hole.
