A Morimi semiconductor "core" is a watt

With the growth of population and the development of economy, the energy demand for housing, service and transportation is increasing. However, the high energy consumption is not conducive to the sustainable development of nature, and our living environment and daily life to bring more and more influence. In terms of reducing energy consumption, the focus has shifted from power plant generators to power outlets used in electrical and electronic equipment. Any technology that can help an electronic device to perform the same function with less energy can be regarded as an energy saving technology, which is of great significance. For electronic and electrical equipment, its energy consumption mainly includes the operating state of the energy consumption and standby power consumption, the proportion of 75% and 25%, respectively. The working condition of electric energy consumption can be regarded as the normal needs of people living and working, even so, the industry continues to develop more advanced technologies and solutions, improve the power efficiency of the working condition, which is a more efficient use of energy. In contrast, standby power consumption is almost entirely a waste of electricity, and this waste is very alarming.

Standby energy consumption is the main source of power waste in electronic equipment, household appliances and office automation equipment. Standby power consumption has two kinds: first, when the power supply is not loaded, absorb the minimum power from the AC power supply, such as battery charger, AC DC wall adapter, etc.. Two is the system light load, but there are still some intelligent functions in the work, such as TV (LED light, the microprocessor waiting for remote control signal), air conditioning, DVD, laptop adapter, etc.. Standby energy consumption is much smaller than the normal function of the device, but it is precisely because the standby state of the device does not play any function, standby energy consumption is a complete waste of energy.

First proposed 1 watts standby energy consumption is the United States Laurence laboratory Dr. Alan Meier. In 1997 he proposed to reduce the target to 1 Watts by 2010. The proposal was adopted by the International Energy Agency, the introduction of the international standby energy consumption reduction initiative in 1999, the target of 2010, so that the standby energy consumption of electrical appliances to less than 1 watts, that is, the "1 watt plan"". The plan has also been a positive response from the EU, the United States and china.

Especially for China, China is not only the world's per capita energy consumption is low, but also the world's output value of high energy consumption in the country, reducing standby energy consumption is imperative for china.

A Morimi semiconductor has been regarded as the focus of energy saving, committed to the development of energy-efficient power management technology and solutions. As such China chip technology certification center, such activities continue to actively participate in and support the A Morimi semiconductor Certification Center, promote the application of the implementation of energy efficient power supply, low standby power consumption of products in the market Chinese, and universal 1 watt standby. In addition, A Morimi semiconductor also with the successful certification center cooperation, in 2006 and in Shanghai in 2007 and Beijing successfully held the two session of the "1 watt forum", caused a strong social response.

The 1 watt forum aims to be the most influential professional and authoritative forum in the field of energy conservation. To reduce the standby power consumption to 1 watts, is not to say that all are the standby power consumption to be reduced to 1 watts, 1 watts of plan "is a kind of sport, one of which is directly related with the 1 watt goal is in the next few years, all electrical appliances, including white goods, black appliances and office equipment can the standby power consumption is reduced to less than 1 watts, but this is not an ultimate goal, the ultimate goal is to lower energy consumption.

In terms of reducing standby energy consumption, A Morimi semiconductor has three major innovations, namely, power management chip innovation, system design and innovation combined with customer applications.

A Morimi semiconductor believes that to solve the problem of standby energy consumption, we must first find out where the loss comes from. This usually includes start-up circuit, drive circuit, bias circuit, output rectifier, magnetic components, etc.. Power management chip can integrate some functions and technologies, for the standby energy sources to develop the corresponding countermeasures to achieve standby function.

High efficient power management chip A Morimi semiconductor solutions with a number of energy-saving technology innovation, including soft jump cycle, function integration, power factor correction (PFC) jump cycle, wireless circle magnetic detection (Soxyless) etc.. Among them, the soft jump cycle as an example, in the past, in the standby mode, the traditional pulse width modulation (PWM) controller without considering the specific requirements of standby, but A Morimi semiconductor NCP1337 enhanced PWM current mode controller with soft skip cycle technology to control the peak current and eliminate some switch pulse, so as to control the switching loss in order to achieve, no load and light load under the condition of high performance.

The two of innovation technology is function integration. A Morimi semiconductor devices developed by the integration of different functions, play a role in simplifying the design of peripheral circuits, but also reduce the power consumption, to help customers easily achieve product differentiation. In addition, another innovation is A Morimi semiconductor in the presence of more than 75 PFC in the case of W, the design of the unique features of the chip to reduce standby energy consumption. Standby, the load is much lower than 75 W, there is no requirement for power factor. In the traditional topology of active PFC, usually adopts the switch type booster circuit (Boost), the switching frequency in the tens to hundreds of MHz, the switching loss can not be ignored.

A Morimi semiconductor introduced fixed frequency current mode PWM controller NCP1230 and quasi
