Buck/Boost Converter - 8-40V to 12V/3A
589 units available with a short lead time.
An industrial-grade DC buck-boost converter that accepts 8–40V input and delivers a regulated 12V output at up to 3A (36W). Ideal for battery-powered systems where input voltage varies — such as SLA or LiFePO4 batteries powering routers, Wi-Fi equipment, or other 12V loads — this module automatically steps voltage up or down to maintain a steady 12V output.
With 85% efficiency, generous heatsinking, and built-in protection, this is a reliable plug-and-play DC-DC solution for a wide range of power conditioning applications.
