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.
Features:
- Input Voltage: 6 to 20VDC
- Input Current: 3ADC max
- Quiescent Current: 12.5mA
- Efficiency: 89%
- Output Voltage Accuracy: ±1%
- Load Regulation: ±2%
- Ripple: 30mVp-p

Jargon buster
Plain-language definitions for the technical terms used above.
- Buck converter
- A power circuit that reduces a higher DC voltage to a lower DC voltage. It is useful when your supply voltage is too high for a module or microcontroller and you want less heat and better efficiency than a simple linear regulator.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- load regulation
- Load regulation describes how much a power supply’s output voltage changes when the connected device draws more or less current. Better load regulation helps keep test circuits powered at the voltage you set, even as their current demand changes.
