I built this portable Lab-Bench Power Supply, small enough to fit in your pocket. It runs on a lithium-ion battery, and can supply anywhere from 0.8 to 22 volts!
This device uses a TPS25730 for USBC charging, a BQ25792 for battery charging, TPS55289 for regulating voltage, and two INA226 chips for current monitoring. Output is protected by a TPS25947. The displays are: HCMS-2973 (Green), HCMS-2974 (Orange).
