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 CO2 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.
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.

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 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.
