Hi,
I'm interested in using the lm3463 with an off-the-shelf power supply, but I'm having a hard time sourcing one with a voltage feedback input that would allow the lm3463 to control Vrail via pin 21 (this pin is an open drain output (current sink) which should connect to the output voltage feedback node of the primary power supply through a resistor and a diode to realize rail voltage adjustment)
Are these generally available or would have to have build this myself? As an example I have been looking at the Meanwell drivers, but none of them seem to support voltage feedback input.
Any pointers would be most appreciated.
Regards,
David
