Dear ADI Expert,
How to calculate the compensation resistance and capacitor of LT3756 on the VC pin?
Are there any design tools for the LT3756?
Thanks.

When the CTRL pin voltage of LT3756 is adjusted to 0.6V, the output is limited to the loss effect, and the maximum output power can only be about 200W
Hi,
LT3756 use Hi Side Sense.
Can it be done by low side?
because of the 100V limit, we can only operate below 100V.
while over 100V, the LT3795 is the only solution.
Why or why not use low side sense ?
Thank you for your kind assistance !
Hi Lech,
Looks like there is no ready solution for this. Best thing is to do a high voltage buck application, probably non-synchronous. LT3761, LT3756-2, LT3795 in buck mode might be able to do this, but not an easy one at almost 500W! You might need a…
Hi
Among regulators LT3796, LTC3779 & LT3756 which is the best regulator to implement a Constant current source with an output voltage of 96V. Suggest if any better regulators are available.

Hello,
if you or your customer check the datasheet page 6 you see following diagram:
You define your LED current by a sense resistor between pins ISP and ISN. LT3756 will regulate on this voltage.
There are more diagrams on this page to show stabilty…
Hope that someone could help me with which device is best to use for the following boost circuit application.
- input voltage is +48V with ±4V tolerance.
- output voltage is 160V
- Boost current should be firmware adjustable through analog voltage…
Using a voltage source to drive a 1A LED string is not the right approach.
Did you look at any LED driver, such as lt3756?
