DC-DC power supply

A simple DC-DC converter power supply board. Takes >=9vdc input and outputs +3v3, +5v and -5v. Uses the relatively (in my world) new buck converter chips. A couple of resistors, capacitors and coils later and we have a power supply. I breadboarded the three volatage circuits individually then designed the board and had it fabricated. A week later the boards arrived and the one I put together worked perfectly first time. Very pleasing. An excellent experience dealing with PCBWay as usual!
