Schematics and PCB layout for a boost converter 0.9V minimum input, 30A maximum input current
Boost converter for an electromechanical cell: 0.9–1.6 V in (up to 28 A) → 12 V at 20 W, biased from a separate low-current 12 V rail.
Open 1v2boost.kicadpro in KiCad 9. The project is fully self-contained — every symbol and footprint lives in lib/, referenced through ${KIPRJMOD}`, so no stock or external library is needed.
LM5155 cannot do this. Its maximum duty cycle is spec'd at 90 % minimum (93 % typ) at 100 kHz. This converter needs D = 0.910 at nominal input and 0.937 at the 0.9 V corner. TPS40210 has no hard duty limit at all — only a 200 ns worst-case minimum off-time, giving D_max…
