I want to know how to generate -2.5V with this part. I read the datasheet and I don't see any reference in how to configure the part.
8.2.3.1 Design Requirements
This design converts 9 V (VIN) to –5 V (VOUT). Adjust RFB2 to set a different output voltage.
if there is a formula to show me how to do the conversion then I'll be set
