## Description

Product Specification: Product Name: 3A DC-DC Adjustable Buck Converter Input Voltage: 4.5V-28V Output Voltage: 0.8V-20V Ouput Current: 3A (max) Transfer Efficiency: 96% (max) Output Ripple: Less than 30mV Switching Frequency: 1.5MHz (max), Normally 1MHz Working Temperature: -45 to 85 degrees Celsius Size: 22x17x4mm Use: Aviation model power supply, DIY mobile power supply, monitoring power supply, four-wheel-drive power supply, camera power supply, communication equipment power supply, etc. Be well-suited for all kinds of occasions with strict requirements for volume and weight. Package Include: 2pcs Mini MP1584EN DC-DC Step-Down Converter Note: You can get a precise output voltage by placing a multimeter on the output and using a screwdriver to adjust the potentiometer slightly.

Review: Seems to work, don't use without a load - Seems to be working after my first test. However, they weren't kidding that you should not have it attached to input power without a load. I let it set for a minute or two before checking the voltage again, nothing was connected to the output power, and placing the multimeter probes on the output leads burned it up.
Review: Very small and works great. - Product works great. I was able to regulate 12V to 3.3V. The product was missing any type of footprint dimensions. I've included picture of the footprint with pin spacing dimensions which seems to work for PCB design.

Product works great. I was able to regulate 12V to 3.3V. The product was missing any type of footprint dimensions. I've included picture of the footprint with pin spacing dimensions which seems to work for PCB design.

### ⭐⭐⭐⭐⭐ Works fine so far
*by S***S on September 13, 2023*

Using to drop 12v to 5v for a water valve for misting system. So, ESP866 (D1 mini) on ESPhome for Home Assistant. 12v Solenoid Valve for 1/4" water valve. 3d printer box for electronics and box is inside house. Water valve mounted in wall outside. Added a Shelley button (awesome) so...one press turns on misters for 15 mins. HA shuts it off. Double press to toggle on off. These buck converters make it easy. The original design for this rig (can't remember where I got the design plan) had a 12v ps and 5v. One for micro controller and one for valve. Buck converter drops to 5v for the D1 mini and works great. Love these smaller bucks too.
