Hi,
I had created a pcb to work with MP175 with respect to the excel I downloaded from the MP175 spec sheet I had decided that resistor but what I am getting is without load above 50v with a simple 0.220 led load it drops to 2.5v what I am missing!
Hello,
Depending on what topology you are implementing and your design, a small load should give better regulation.
I recommend checking the application section to check your schematic. You can monitor Vds, Vout, and Iload as well.
Best Regards,

Hi,
Thanks for the response but even without load itself it had to give constant 5v right but the current o/p I am getting is 50v after adding 1k resistor with led it drops to 5.9v if I add further 250mamp microcontroller load it further drops to 2.2v it was not staying in constant voltage even with its own resistance of 68k as a o/p resistance load.
With regards,
