Tool/software:
Hi all,
I am trying to recreate the inverting buck-boost converter with the lmr33640 as shown in application note "Working With Inverting Buck-Boost Converters", snva856b. But i am having a hardtime getting no negative voltage output of the converter. This is my first time using PSpice, so it may be something wrong with my setup but i do not think so. Simulation is setup very standard with Time Domain, 1000ns run to time.
I usually just use Webench, but it seems to not support inverting converter for LMR33640.
Any one that could point me in the right direction? (Whenever i get this going, what i am actually are looking for is +12v to -15.5v @ 1.5A)
