Green and efficient is the eternal theme of electronic products, and power IC has been playing a very important role in it. Due to the increasing popularity of low power portable products, energy saving and environmental protection requirements, the demand for power management is also increasing. Now, such as panel driven IC, household appliances, LED lighting drive IC, charging device and so on, has become an important field of power IC, how to reduce power consumption and thinner power consumption through lower power consumption Short and low cost have become the direction of manufacturers' efforts. This is a great responsibility for the power IC.
Because of the technical innovations made by PI in high voltage integrated circuits, it has achieved small size, compact structure and efficient power supply for all kinds of electronic products, including LED lighting, mobile charger, computer, LCD TV, DVD player, set-top box, home appliance, telecommunication network equipment, and other more applications. High efficiency power supply. For example, PI's CONCEPT IGBT drive can improve the efficiency, reliability and cost-effectiveness of high-power applications, including industrial motors, solar and wind power systems, electric vehicles and HVDC transmission. Since its publication in 1998, PI's EcoSmart energy saving technology has saved billions of dollars in energy consumption and avoided millions of tons of carbon emissions.
Doug Bailey, vice president of PI global marketing, said that standby power has become a major driving force in the power IC industry. Since many devices are always in a "energizing" state, the devices that consume minimal energy in the sleep mode are very attractive when the battery life is considered. This may require a power IC to work in a variety of modes so that IC can perform work in a more efficient way when the device is not used and when it is fully operational.
Energy efficiency regulations promote the development of power products
The efficient use of electrical energy has become a trend of development. Solutions to improve efficiency, reduce power demand or prolong battery life will occupy an important position in the future. And the standard standards of energy efficiency in all countries are also evolving. Electronic manufacturers need to meet the standards of various countries and introduce more efficient power products to win market recognition.
Driven by institutions and government norms, all power manufacturers actively develop innovative solutions that can improve efficiency, including reducing standby power, improving efficiency and power factors. Mr. Doug Bailey says that all energy efficiency laws around the world are binding on manufacturers of almost all kinds of products (from TV to air conditioning, mobile handheld devices, to electric cookers, electric toothbrushes, and lighting systems), and require them to meet the more stringent power limits. This means that designers must find more efficient power designs. Some IC products launched by Power IntegraTIons have the highest energy efficiency on the market, which can make the power supply easily meet all international regulations.
The demand for efficiency and reliability in the future power management system will be higher and higher, which requires designers to accurately grasp the market dynamics and regulations, and to innovate the power supply scheme in time.
The rise of portable devices raises new requirements for power management.
One of the most important growth opportunities at the present stage is in the field of mobile devices. Battery powered mobile devices have high requirements for battery charge and discharge management, and must be compact, efficient and low-cost, which leads to mobile power management technology to integrate more functions on smaller silicon chips and achieve stronger system power use with higher design flexibility, without increasing cost. In the future, the development of mobile power management products will focus on energy saving and consumption reduction. The power supply design cycle is accelerating, standby power consumption, energy efficiency improving and the requirement of plate area decreasing are changing the traditional power design method.
In addition, almost any battery powered consumer equipment uses a color active matrix LCD to display the different information and data required by the user, and the challenge for the manufacturer is to ensure that the user can read information from the display in any environment. To achieve this goal, manufacturers must provide color LCD with proper backlighting. This backlighting is usually provided by white light LED. This leads to the need for compact, efficient and low noise methods to supply these LED.
With the development of electronic technology, especially the popularization of portable products and the promotion of energy saving and environmental protection, the power IC plays a more and more important role. A few years ago, the power IC was only integrated voltage regulator and DC/DC converter, but now the power IC covers a lot of content, including AC/DC, DC/DC, LDO (low voltage differential voltage regulator), battery charge and discharge management, PWM controller, Reset, PFC (power factor correction), energy saving control, power MOSEFT and so on. The development trend of power IC now is not limited to single function, but integrates all kinds of functions. The trend of integration is obvious.
Doug Bailey, vice president of PI global marketing, said that our increasing dependence on mobile devices is another factor driving the development of power IC. Now, users have been heavily dependent on smartphones, not just for calls, but they don't want to wait 4 hours, or even longer, to fill the phone with their phones. Qualcomm and other mobile chip companies are launching a new fast charging protocol, which makes power IC manufacturers begin to rethink their solutions.
All these factors bring new challenges to IC manufacturers of power supply.
