The meaning of the term "high power LED" is rapidly evolving. Although a 350mA LED could easily earn the stamp of "high power" a few years ago, now, 5A to 40A LEDs and laser diodes are used in the DLP projector, surgical equipment, stage lighting, automotive lighting and other applications traditionally served by high intensity bulbs. To meet the light output requirements of these applications, high power LEDs are often used in series. The problem is that several series-connected LEDs require a high voltage LED driver circuit. LED driver design is further complicated by many applications that require fast LED current response to pulse width modulated (PWM) dimming signals.
The new LT®3763 (http://www.linear.com/product/LT3763) is a 60V synchronous, step-down DC/DC controller designed to accurately regulate LED current at up to 20A with fast PWM dimming. It is a higher voltage version of its predecessors, the LT3743 and the LT3741. In addition to higher voltage, the LT3763 has 4 regulation loops that make it easy to design highly efficient, versatile and robust circuits.
I enjoy your presentation of the LT3763 high powered led dimming .
I am present trying to draw a circuit for this LT3763 to enable me make a circuit board. but am not very perficint in this area .
Could you supply me with a circuit board print out of the copper side and the silk side to enable me to make my board using the LT3763.
Thank you Greg
Trading stocks typically have the lowest fees on eToro, which is one reason why I recommend you stick to this market when starting out.
All trades charge both a spread and daily rollover fees.
It really comes down to individual trading strategies and preference. But to give you an idea, I tend to hold on to stocks for a minimum of 6 months and all other trades tend to have an average duration of about two-three weeks.
A final word on over-trading.
This is a point that I want to expand on a little more, specifically in relation to copying other traders. Below is a screenshot of my equity chart over six months. The red line shows the number of people copying me.

The same holds true for the stock market in general.

How to Start Trading Cryptocurrencies.
Cryptocurrency trading can be extremely profitable if you know what you are doing, but it can also lead to disaster. Even though most traders decide to either go with fiat or bitcoin, other cryptocurrencies can represent viable income sources, as long you as you tread carefully and understand what you are doing. This guide is for those who want to start getting involved in cryptocurrency trading.
