## 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.

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐⭐ Used these to power an Apple TV from 12V.
*by J***N on December 22, 2023*

I used these to modify an Apple TV to work from a cigarette lighter without using an inverter. Have had them installed for about 3 months and the Apple TV is working great. the adjustments on them are very small so you have to be careful when turning with a tiny screwdriver.
