Is there some indication on how the feedback loop on the LTC3803 parts should be done? at least some starting point.
The datasheet says that an RC series has to be connected to ITH/Run but I have never seen a compensation network between the output and…

Hi ADI Experts

I am using LTC3803 for POE at application. but I have some inrush current issue that needs to be reduced.

since the SS is internally controlled by LTC3803, May I know if it is possible to build a external SS circuit on Ith pin?

Does ADI…

I designed PoE power supply with using LTC3803, and it's work fine in non-isolated variant, but  i have problems with isolated variant. 

Schematic of isolated variant:

It doesn't work the way I want it to. By changing resistors R41 and R43, I cannot…

How does the LTC3803 Flyback controller prevent the output from exceeding the desired output when there is no minimum load?

The datasheet for the LTC3803-5 has a "Dual Output Wide Input Range Converter" on the front page. Would this circuit work on the LTC3803-3. I need a 3V@150mA output and a 12V@10mA output. I don't see such a circuit on the LTC3803-3.

Thank…

Hi 

I am looking for a isolated DC/DC converter 

May I have your suggestion for my system

the spec is as below

-------------------

Input Voltage: 41V ~ 60V

output voltage/ampere : 19V / 2.63A ( 50W )

current consumption @ NO Load <10mA
