Part Number: LM22678 Hi team,
My customer wonders why the inverting regulator application is deleted from the datasheet.
He's using LM22687 for inverting regulator application so he wants to check if there's any risk.
I recognize this was discussed…

Part Number: LM22678 Hi support team,
I have some questions about the LM22678. Our customer is considering using LM22678.
[Questions] 1. Can LM22678 be used as an inverting converter? (For example, 12 V to -5 V output) I’m concerned that "4 Revision History…
Part Number: LM22678 Other Parts Discussed in Thread: TEST
In the above circuit
VIN 4.5V
Rfbb = 1k Ohm
Rfbt = (Vout/1.285-1) * Rfbb
Rfbt = 1.568k Ohm
When applied
VOUT does not output 3.3V.
Please explain.
Thank you.
