400Vin to 250Vout DC/DC

Other Parts Discussed in Thread: TINA-TI, LM25088

Hello specialist,

I made idea for high voltage input DC/DC. Requirements are;

Vin : 280V - 400V
Vout : 250V
Iout : 1A

I draw the schematic on TINA-TI, however it was can not run.
If TI's engineer has any concern watched this schematic, I want to have that opinion.

Hello,

If you connect the SW pin of the controller to the source terminal of the external MOSFET you should be able to get some voltage at the output.

Hi,

Did you have that see the TINA schematic? SW pin of LM25088 is not connected to FET source. That is connected to GND.
