STD 5V Boost Regulator

Most boost converters only switch off the boost function when disabled, still allowing current to flow through the output via the inductor and the diode. This board uses the FP6277, a synchronous boost converter, that completely switches off the power at the output when the enable pin is pulled to ground. This is great for battery-powered projects that uses sensors that need to be switched off when not in use.
With supply chain shortages making it difficult to get hold of even simple components like DC-DC converters, I wanted to design a breakout board around a chip that's easy to source from suppliers like LCSC. At the time of writing (2021-01-07) there are still more than 28 thousand FP6277 chips in stock at LCSC.
