It seems the matter is that LT3956 limits SW current
A customer's question: "How does the buck mode schematic on page 18 of the LT3956 datasheet map to demonstration circuit DC1521A? I want to modify the demonstration circuit to be a buck mode LED driver according to the datasheet schematic just…
My LED specifications are:Size: 34*34*1.0mmPower: 100WCurrent: 2AVoltage: 70-75VPeak Irradiance: 8W/cm2Viewing Angle: 60 degreeChips Arrays: 40 chips, 20 in Series 2 in Parallel
I have searched it out LT3755 and LT3956 but need some expert opinion.
Would an arithmetic expression of a data seat be right?
When the price is input and I Calculated, it won't be 4.7 μF(boost mode) ,(my calculation result is 10 μF )
And buck mode,my calculation result is 11.75 μF
A customer asks, "Is there a simple way to operate boost demonstration circuit DC1521A as a buck mode? I am familiar with boost circuits but buck mode is a little new to me and I want to see a buck mode circuit operating in front of me before I invest…
