The MP1584EN DC-DC Adjustable Buck Converter is a high-efficiency step-down module designed to convert higher input voltages (4.5V to 28V) into a stable lower output voltage (0.8V to 18V). Capable of delivering up to 3A continuous current, this compact module is ideal for powering microcontrollers, LED drivers, battery-powered projects, and other electronics requiring regulated voltage. With excellent line and load regulation, over-current protection, and high efficiency, it is perfect for DIY electronics, embedded systems, and power management projects in Bangladesh.

Features:

• Wide input voltage range: 4.5V to 28V DC.

• Adjustable output voltage from 0.8V to 18V.

• High efficiency up to 92% for energy-saving operation.

• Capable of supplying continuous output current up to 3A, peak current 4A.

• Programmable switching frequency: 100kHz to 1.5MHz.

• Pulse-skipping mode ensures stability with ceramic capacitors.

• Internally set current limit without external sensing resistor.

• Cycle-by-cycle over-current protection for safety.

• Input under-voltage lockout for stable operation.

• Compact and lightweight design (22mm x 17mm x 4mm) for easy integration.

• Reliable operation over a wide temperature range (-40°C to +85°C).

How to Use:

• Connect the input terminals to a DC power source between 4.5V and 28V.

• Connect the output terminals to the load or device requiring regulated voltage.

• Adjust the output voltage using the onboard potentiometer to the desired value.

• Ensure the load does not exceed 3A continuous current to maintain safe operation.

• Monitor output voltage with a multimeter when setting the voltage for precise adjustments.

• Integrate into Arduino, Raspberry Pi, or other electronics projects requiring stable DC power.

• Use in LED drivers, battery-powered devices, robotics, or DIY electronics circuits.
