Industrial, business and automotive applications are not the same requirements, as their environmental conditions are different, and the requirements for the use of sustainability, security, and reliability are different.
The business environment is basically the environment of human daily life. We must feel comfortable when we stay in these places, otherwise it will be away or improved. In the experience of my personal experience, because living in Shenzhen, most of the year will be more hot, once it feels more comfortable, it will find that the temperature is below 29 ° C, and it will be added to the 22 ° C. Dress, otherwise it will often have a feeling. If you want to go to Hong Kong, even if you are in summer, you must prepare your coat, because people will open the cold air even in the hot days, this is likely to be with people like wearing a habit Adapt, but this is just my own guess, it is not true.
Although people from all over the world may differ from the definition of the business environment, it is often said that the room temperature is more than 20 degrees of Celsius temperature. Most commercial devices define the test temperature to 25 ° C. It is really just right. This temperature can be Let us feel comfortable, in the middle of the commercial temperature range of 0 ° C ~ 70 ° C, almost all electronic components can meet the requirements.
Our recent RT (Q) 6363 60V / 3.5A non-synchronous Buck converter, the RT6363 obtained after the q in the model is the commercial models. If your application only needs to meet the needs of business applications, RT6363 and its same series of RT6360 (0.5A), RT6361 (1.5a), RT6362 (2.5A) and RT6365 (5A) are the best options for your needs. These devices provide two packages in PSOP-8 and WDFNs to meet your needs of different features and dissipation power.
Most industrial environments are also indoor environment, but it is difficult to implement environmental regulation in these environments. I have played over the IC industry and has been in the cement industry for many years. I have been almost open, even if there is a door and window, there is no air conditioning available, and the summer workers often need to use the fan to cool down. Winter is very cold, the electric furnace is the best air conditioning equipment at that time, but the equipment that placed in open space is unable to enjoy this treatment, they can only be with the natural environment.
The routine definition of the industrial temperature range is -40 ° C ~ 85 ° C, the temperature definition of the AEC-Q100 Grade3 suitable for the automotive industry is also this range. This definition is basically suitable for the indoor environment for the cockpit, but this room is more than the aforementioned Indoors should be much worse at some point.
RTQ6360 (0.5a) ~ RTQ6365 (5A) is a device suitable for industrial applications, and the working environment and work junction temperature range defined are -40 ° C ~ 125 ° C, this definition has exceeded the above industrial temperature range, so satisfaction The need for industrial applications is completely no problem. Take RTQ6363 as an example, its specification is to define its parameter test temperature range:
The highlighted portion in the figure indicates TA = TJ = -40 ° C to 125 ° C, which means that all parameters in the table below meet specifications in this temperature range, and anything that is included in the specification is quite So one of the contract contents signed between risks and customers, so the quality of customers in using these products is really safe.
The products used in vehicles are significantly different from those used in other occasions, which is determined by the particularity of the vehicle environment.
Automakers are completely unable to determine which customers will open their own wheels, and extreme destination may be high and deficient, or the heat is high. I stayed in Shenzhen, it belongs to the environment and hot places. Summer sunshine can expose the inside of the car to a very high temperature. I have experienced the seat of the car as a hot fitting equipment. At that time we just From an air conditioner, it is very cold. It feels that it is frozen. I have to deliberately put the body in the seat. The chill is so fast, so this experience is very Positive, but for those electronic devices that are nowhere in the car and their composition elements are another matter, high temperature will make their life expectancy obviously, it is easy to invalidate early.
The electronic equipment used by modern cars has increasingly, and the microprocessor can count to hundreds of hundreds. The electromagnetic compatibility between the equipment will become more and more prominent, and the chances of quality problems in the whole vehicle have also increased, all The device needs to move toward zero loss, and the power management device we provide naturally also meets this requirement, but it is not only a long-term reliability, but also works very stable and quiet, neither impact on other systems. It cannot be easily affected by other systems. It is very determined to provide the determination of the vehicle to provide full range of product services, so the formulated quality control indicators are also very strict, such products that start delivery from 2012 have been widely adopted by many international plants. RTQ2960-QA ~ RTQ2965-QA series products are all new high-voltage Buck products that meet the requirements of the car, all of which have passed AEC-Q100Grade Level 1 certification, and can work long and reliably within -40 ° C ~ 125 ° C The operating voltage range of 4V ~ 60V is high. The ability to throw the load voltage impact is as high as 65V; the load capacity can reach 0.5A to 5A; the operating frequency can be adjusted between 100 kHz to 2.2.5MHz, or 300kHz ~ 2.2 The external clock signal of MHz performs synchronous control. In order to improve electromagnetic compatibility characteristics and safety, all of these devices use the PWM adjustment technology of extended spectrum, and all of the pin layouts are in the result of FMEA failure mode and their utility analysis, all have adjacent pin short circuit protection functions, ensuring long-term use. Safety.
The content shown in the above table is that I have obtained the data sheet obtained by the parameter search function of the establishment of the Trich website www.richtek.com, and the identical content has been synthesized by me to become a project, so that This table looks simple. In fact, these three series of products can be replaced with each other, all parameters, the same components can be directly replaced to achieve new performance indicators, which gives the convenience brought about by management in use. I believe it can bring direct value to some customers.
