## Description

This is a high grade DC Buck converter that inputs 6 to 12V and outputs 5V up to 3A or 15W. With good thermal performance and protection, this DC block is perfect for battery applications (such as SLAs or LFPs) that need to power a USB or 5V device even while the input is varying (battery charge/discharge). 89% efficiency makes this a high-efficiency, plug and play, DC Step Down solution.

If you need to plug it into a car, check out this [male automotive socket](https://core-electronics.com.au/anderson-to-merit-plug-adaptor-lead-8awg.html), and cut the Anderson connector off.
