Created a design with the LM22676, but after simulation the circuit has gone. Also the PCB layout is for another chip, LM26xxx

is this a known problem?

Hi Phil,

Thanks for sharing the design. Please note that I am able to view the circuit after simulations.

Regarding PCB, this board is designed for multiple components and this works for LM2267X-5.0 as well.

For 5V operation do not place Css, Rfb1 and use zero ohm resistor for Rfb2.

Thanks and Regards,

Atul
