Overview

Power supply is an open-source printed circuit board by ericmullally, from the ericmullally/power_supply repository on GitHub, published under the MIT licence. It is a 4-layer board of 59.7 × 65 mm with 60 parts on 70 nets, routed with 141 tracks and 42 vias.

It is built around the TPS63070RNMR, PTV09A-1015U-B203 and XFL4020-152MEC. Its parts include 27 capacitors, 8 resistors, 5 diodes, 5 connectors and 3 ICs. It belongs with the power boards and the STM32 boards of this library.

power_supply

Simple build for a Breadboard power supply.

Major hardware

STM32F401 MCU.
VIM-878-336640 LCD.
BU91797MUF-ME2 LCd Driver.
tps63070 Voltage regulator.

Details

The power supply is meant to provide voltage in the 1V - 8V DC range to a user breadboard. It uses either a USB type B connection or a power jack connector not to exceed 16V. The tps63070 is rated to supply up to 2 amps of current depending on the input and output voltages (see Docs->ICs for datasheet).

Documents

Attached is the basic code written for the STM32Ide version 1.11 using the HAL library. The driver for the LCD display, along with the schematics for the board (for KiCad) and relevant datasheets.

Questions

How big is the Power supply PCB?

It measures 59.7 × 65 mm and has 4 copper layers, 1.6 mm thick.

What parts does the Power supply use?

60 parts, built around the TPS63070RNMR, PTV09A-1015U-B203 and XFL4020-152MEC. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Power supply KiCad files?

From the ericmullally/power_supply repository on GitHub, at the commit this page was made from: the board is KiCad/Power_Supply.kicad_pcb and its schematic KiCad/MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Power supply design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
