Other Parts Discussed in Thread: TINA-TI
Tool/software:
I am running simulations of this IC on both LTspice and TINA-TI. I have used the same values and circuit as shown in the TI power designer (Webench). The simulations on Webench show that the output voltage is 3.3 V, whereas the same circuit on both LTspice and TINA-TI show that the output voltage is 2.9V. No changes in the feedback resistors is changing the output voltage above 2.9 V. Is there any mistake in the spice models or in the circuit suggested in the datasheet and Webench designer?
All circuits and values for the components are as suggested in the datasheet.
