TPS65131 Split-Output Booster Supply Generating a negative voltage over -5V is kinda annoying: most chargepumps max out at 5V inversion, and ones that can double-then-invert like the MAX232 aren't high current. We bumped into the TPS65131 (https://lnkd.in/eSeJ9D8W) while working on our Floppsy design (https://lnkd.in/ePzF6HNQ) - we need -12V to bias the Apple Disk ][ drive control system. It's a combo buck and boost: give it 3~5VDC and give you up to -15V and +15V output. The split supply part is particularly nice because you'll want +-12V or +-15V for analog projects. This standalone power supply breakout has two mini trim pots to help adjust the output voltages on both sides so you can have as little as +/-6V and up to +/-15V. With the 2A internal switches, you'll get a fair amount of current on either rail. #electronicsdesign #voltageconversion #tps65131 #powersupplydesign #analogprojects #diyelectronics #hardwareengineering #boostconverter #negativesupply #positivesupply #dcpowersupply #electronicscomponents #circuitdesign #powersupply #electronicsengineering #diyhardware #analogcircuits #voltageregulation #techgadgets #opendesign #opensourcehardware

About us
Adafruit was founded in 2005 by MIT engineer, Limor "Ladyada" Fried. Her goal was to create the best place online for learning electronics and making the best designed products for makers of all ages and skill levels. In the last 15 years, Adafruit has grown to over 100+ employees. Adafruit has expanded offerings to include tools, equipment, and electronics that Limor personally selects, tests, and approves before going in to the Adafruit store. Adafruit is a 100% woman owned manufacturing company, a certified Minority and Woman-owned Business Enterprise (M/WBE), a certified Women’s Business Enterprise (WBE), and WOSB. During the COVID-19 outbreak Adafruit Industries is operating as an essential service and manufacturing business: NYC – Executive Order 202.6 making PPE and medical device components. Adafruit was appointed to the Small Business Sector Advisory Council by the City of New York to help restart the NYC economy. Post pandemic New York City launched a new Industrial Working Group which Adafruit is Co-Chairing, bringing together leaders from across the city’s industrial and manufacturing sectors with academics and policy experts to redefine the sectors’ needs and opportunities. In 2024 Adafruit moved to Industry City! Brooklyn, New York! Industry City is a six-million-square-foot ecosystem in Brooklyn, NY - a bustling workplace for professionals across multiple disciplines including USA advanced electronics manufacturer Adafruit Industries! After hours and on weekends, Industry City becomes Brooklyn’s unofficial backyard, offering live music, festivals, dining, and tons of retail.

bq25185 + TPS61023 = USB or Solar lipoly with 5V output 🔋☀️🔌 We spent the weekend tweaking our bq25185 (https://lnkd.in/e8369MXn) designs and made one basic breakout for this flexible battery charging chip. Then, we made a board with a 3.3V buck output to charge the battery with a USB or solar panel and got a clean and consistent 3.3V out. With both of those working, here's a design for a version that has a 5V booster with the TPS61023 (https://lnkd.in/e3z6Mx2R), which gives a nice clean 1A with a small bill of materials. Now you can use USB, DC, or solar to charge your favorite lipoly or liion chip and get 5V output. Maybe we'll make a version that can handle 3.6V LiFePO4 batteries, too? It's easy to set the bq to handle those by changing a single resistor. #lipoly #usbcharging #solarcharger #5voutput #tps61023 #bq25185 #diyelectronics #makerproject #powersupply #breakoutboard #batterytech #liion #cleanenergy #boostconverter #electronicsengineering #embeddeddesign #diybattery #solarcharger #solarpower #electronicsproject
