15Pcs 5V Regulator Module Mini DC-DC 4.2-24V to 5V 3A Step Down Power Supply Module Voltage Reducer Voltage Buck Converter Adjustable 1.8V 2.5V 3.3V 5V 9V 12V Power Supply Transformer Module

Description

• Voltage buck converter input voltage:DC 4.5-24V; Output Voltage:integration adjustable and fixed output,back side can choose fiexd output voltage, adjustable Range:0.8-17V,fixed voltage (1.8V 2.5V 3.3V 5V 9V 12V)
• 5V 3A step down power supply module uses synchronous rectification circuit conversion efficiency is very high, efficiency up to 97.5%
• DC-DC 12-24V to 5V 3A adjustable step down power supply module ultra-low quiescent current, quiescent current of 0.85 mA
• Output integrated adjustable and fixed voltage,you can get fixed output voltage by soldering the pot on the board.If the fixed output voltage is not what you want, you can adjust by potentiometer
• Note: The default output is an adjustable voltage. If you need to fix the output voltage, use a knife to cut the wire in the red circle on the product image
