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.
Features:-
-
Current consumption is reduced with use of the burst mode, promoting standby compatibility with a single converter.
-
The optimized switching device provides ideal partial resonance operation for high efficiency and low noise.
-
The 900V resistant switching device (high-speed IGBT) simplifies design of power supplies for worldwide input.
- Power consumption under micro-load is extremely low (burst mode).
- Use of a drain kick circuit eliminates the need for a start-up resistor.
- The use of a soft drive circuit reduces noise.
-
Incorporates an over-current protection function (primary current detect, Ton limit).
-
Incorporates over-voltage protection and thermal shutdown functions.
-
A power supply circuit may be configured with the minimum of external components.
-
The use of the fully molded package is beneficial for insulation design.
