DC-DC Converter
Hi, I have recently built a dc-dc converter to convert supply voltage from 6V to 32V, the circuit diagram is as below: and the circuit on the breadboard is looks like this: My friend has built one with the same circuit diagram, I have double checked with him, both circuit connects exactly...- Joe Wu
