I am using LT3757 High Voltage Flyback Power Supplyin one of my designs, TDK DCT15EFD-U44S003 transformer recommended is obselete, is there any alternate recommended.
I need to generate voltage upto -100/ -200V.
Look forward for an immediate response…
You may want to take a look at LT3757.
I am interested in using the LT3757 to build a boost converter (that'll be powered by batteries later) in discontinuous mode. However it seems that most of the data sheet related to the LT3757 is about continuous functionality. If someone could specify…
I would like to do a small signal ac analysis of the LT3757 to get the gain phase both open loop and closed loop. Is there a small signal averaged model for a SEPIC under current control that I can use that will run on LTspice?
Please check out the LT3757 LTSPICE files at:
I have an application using an LT3757 powered from 3.3V with a switching FET power from a separate higher voltage supply. The application circuits for the device show a direct connection between the gate drive of the LT3757 and the gate of the MOSFET…
I'm currently using the LT3757 as a flyback controller and specification sheet outlines (page 20, snubber section) this for calculating Ccn:
However, Rcn is not mentioned anywhere in this section. Is Rcn a typo and should be Rsn as mentioned…
I am using LT3757 flyback converter application and run the simulation in LTspice.
I want to use LT3757 convert 12V input to 180V. The SCH is same as the example in datasheet, which shows below, and i changed the 16.2K resistor to 31.4K Ohm.
I'm trying to design LT3757 sepic converter. However, while the output is not good while simulating load transients.
I have attached .asc here. Could you please help improve it?
Thanks in advance.
I have done a LT3757 demo board based on flyback transformer, want to generate an ouput >2KV. I found that When I add a small parallel capatance on divider resistor on PIN FBX, it works.
but when I change the divider value of the resistor, the output…
