5vpol
About the 5vpol PCB
5vpol is an open source PCB design by fullyautomated, published on GitHub. It is a 2-layer board measuring 42 × 25 mm, with 24 components from 21 distinct parts.
Other key parts include the TPS62135. By type, the board carries 7 capacitors, 6 resistors, 2 connectors, 2 diodes, 1 IC and 1 test point.
From the project
16-V Input 3-A Output Point-of-Load High Efficiency DC/DC Converter
This design is based around the Texas Instruments TPS62135 converter. IC Datasheet. Board Schematic. For layout, see the .kicad_pcb file in the repository.
Connect the input side to the power source, and the output side to the load. The converter powers on automatically above 3V input. Output is programmed to 5.0 volt, can be changed by replacing R2 and/or R3. Reference voltage is 0.7 V. Supported input voltage is around 16 V max., above which the D1 TVS diode will start to clamp. You can remove this to increase maximum input voltage to 18V abs max, but then you should avoid hot-plugging the…
