I am having issues with generating 50V from 4-24V input.
I changed the feedback resistors to a higher value but the same ratio. and 48v was there for a while, and then the component failed again.
I am debugging a design that was handed down to me.
The initial differences I see are that the FB resistors were smaller in value (same ratio) and I changed this to match the simulator.
Also we are using CDS19534 components instead of the simulator recommended parts, and finally I see that we are not sampling the current but rather have .02 ohms to ground, but the drop across the resistor is not fed to the chip.
Finally the person before me did not have Bias tied to .1uF cap, but it is now.
It seems to me the part is having an over voltage failure.. but without knowing.. it's a guess.
