Hello All,

   

 

   

 

   

I'm working on a design that uses a PSOC5LP and I haven't been able to find information that says if it's required to hook up the boost converter. I don't need the feature in my design and would like to know what has to be done to disable the converter. 

   

 

   

 

   

Any help is appreciated,

Short answer: when you supply normal Vdd the boost converter is not used.

   

For the long asnwer look at the AN Dana posted, and look at the TRM and the datasheet which will tell you how to connect the power rails properly.

Thanks for nudge in the right direction.

   

I was able to find this snippet on page 7 of the AN

   

If the boost converter is not used, tie the VBAT, VSSB, and VBOOST pins to ground and leave the IND pin unconnected
