Note: The DC-DC boost converter models are all here, check the parameter carefully from the table and select the right converter power supply when place the order.

Tips: What can a DC-DC buck-boost Converter do?

The DC-DC buck-boost converter can regulate and stabilize voltage by either increasing (boosting) or decreasing (bucking) the input voltage to maintain a constant output voltage. It is especially useful in systems where the input voltage can vary widely, such as in battery-powered devices, solar panels, or automotive electronics, ensuring the connected components receive a steady voltage regardless of changes in the power source.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
