Category: Datasheet/Specs
Product Number: LTM8045
Below is my circuit, I am attempting to convert +5V into a -11.5V output:
The FB resistor is calculated using the formula in the datasheet to be 138.1Kohms.
Why is FB regulating to -8mV? Is my circuit incorrect or is this a model issue? Are there considerations with my circuit design that I missed? Vout is around -11.6V, not the -11.5V that was set.
Edit Notes
Added output voltage clarification.[edited by: Yibo at 7:00 PM (GMT -4) on 18 Jun 2026]
