Now more and more IC design manufacturers have joined the LED design team, designed a number of models, here from the performance price ratio in detail, how to choose their own suitable IC, which IC is most suitable for their own products.
For IC design companies to understand what kind of ICs the market needs, what price should be suitable. Prices can only be changed at any time. Quality and price are the factors that determine whether or not to use, and it is important to meet the product design quality parameters! The price is more important!
1. LED driver IC-AMC7150 with mixed market
At that time, AMC7150 was still good. I thought about it or not. It has a very important factor, that is, the price. There is a market price of less than 2 yuan, which is the reason why you use it. The AMC7150 currently has dozens of IC models that can be directly replaced, and the price war will be unavoidable.
It can be selected in low-voltage 4-25V products with low design parameters, and the basic drive capability is designed below 3W. For example, 1W string 3 or 3W 1 LED design is stable.
2, Hangzhou Silan Microelectronics - SB42511
At present, Silan Semiconductor has introduced a new IC, which is mainly aimed at driving a battery with 24V to drive 6 LEDs . The price is higher than the AMC7153 discount in the European and American market IC, suitable for designing 1-6 LEDs, input 6-25V input voltage, SOP8 package form, mainly for the current low-end spotlight market.
Crane Control Station also called Rainproof Pushbutton Switches, is a newly developed products, which is beautiful , strong and light, reliable struction, advanced and big contact capacity; mechanical interlocking , and if necessary, it can achieve interock circuit to assure the more safety and reliable using . The products matched cable jacket and waterproof rubber sealing strip, have a good (IP65 level) performance of dust and rain. So it most suitable for the remote controll in outdoor, rainy and snowy, dusty and damp environment, such as electric hoist, open conveyor blt, building line etc.
