hello
I want to make a 15v dual power supply from a buck boost converter I bought on ebay
step up
I connect a 9v battery to it and get 32.8v max. I have two resistors making a divider. the resistors are 383kohm.
I measure 32.8v across the supply, I have these outputs (+-) going to breadboard connected to the resistors. the supply at the breadboard is 32.7v and across individual resistors 13.7v
so it is loosing some volts somewhere. I went up to 32.8 from 30 as I wasn't getting the output across the resistors that I wanted. I still cant get it at 32.8v
any suggestions on this?
thanks
simon
