What is MC1489 for?

Since LEDs are current devices, they need a power supply that can provide a stable current to power them.

LED driver power supply is a constant current power supply designed according to the characteristics of LED.

In addition, the LED driver source can adjust the output current to change the LED brightness.

It is a photoelectric coupling, and its main role is to play the role of photoelectric isolation.

Development environment configuration.

Development cycle. Development funding.

Personnel level. Team organization.

Outsourcing capabilities. You can use the CMM Capability Maturity Model to give an overall score.

I advise you to make up for the hanging classes, the diploma is a stepping stone, in fact, after entering the unit, no matter what academic qualifications you have to do, it is very easy to do the work, it depends on whether you can enter. I'm an electronics engineer and just graduated as an assistant engineer.

Learn more in school modulus and high frequency, many people don't like to learn high frequency circuits, like those digital electricity and DSP and the like There are too many, as long as the engineering colleges will be. I like to write programs on my computer and so on. And there is a shortage of high-frequency talents.

Now the salary of high-frequency talents is very high!

If you can prove that your protel kung fu is very deep and has good experience, you can still find a job, and the salary may be two or three thousand, of course, the high level may have a lot more salary, and the general level is at this price, or even lower.

In fact, Protel is only used in school, and it is the most basic tool for drawing circuit diagrams, and PowerPCB and so on are generally used in work, so I think it is very difficult to find a job with only that skill!

You don't have a diploma recognized by the state, and you won't be able to find a job easily.

Because there are too many people who teach themselves a certain specialty!

Let's start at the lower level.

The direction is an electronics engineer.
