If you have a single battery with 1.5v or 2v, do you want to work any 3V circuit or device using this single battery? this boost converter circuit do that. in this article i’m sharing about how to build a 1.8V to 3.3V Boost Converter using the BL8503 IC. This IC is a small and high efficient step-up regulator and it is a best choice for any single battery powered projects. if you have any plan of building tech, IoT gadgets, or portable sensors the BL8503 circuit is the best option for converting low input voltages to a stable 3.3V output. Learn about the circuit diagram, component required and pinout information of BL8503.
