Hello,

I want to use the LT3680 in inverting buck boost topology to generate -15V@0.5A from +5V input voltage.

I simulated the design with LTSpice (attached), and everything looks ok, efficiency is app. 78%.

But according to some application notes, the…

Hello,

I willing to imlement PSU with buck converter with LT3088 LDO and looking at example in datasheet p26 I see one portion of circuit which is of unclear function. Could someone explain what it does and how it works?
