MP1584EN Ultra-Small 3A Fixed 5V DC-DC Step-Down Buck Converter

The Fixed 5V Edition of the MP1584EN buck converter is a high-frequency, synchronous step-down regulator optimized for delivering a rock-solid 5V output for microcontrollers, sensors, and USB-powered devices. By utilizing a fixed-resistance feedback circuit instead of a mechanical potentiometer, this module eliminates voltage drift and is highly resistant to vibration, making it the preferred choice for flight controllers, robotics, and automotive electronics. Despite its miniature 22x17mm size, it can deliver up to 3A of output current with exceptional efficiency. The 1.5MHz switching frequency ensures a clean, low-ripple output, while integrated thermal and over-current protections ensure the safety of your connected 5V components.

Key Features:

• Fixed 5V Output: Precision factory-set output ensures your 5V logic remains safe from accidental voltage spikes or drift.
• High-Current 3A Capacity: Powerful enough to drive multiple servos, high-power LEDs, or an Raspberry Pi.
• Superior Efficiency: Converts higher DC voltages (up to 28V) to 5V with up to 96% efficiency.
• Ultra-Compact Design: One of the smallest 3A buck converters available, perfect for weight-sensitive drone builds.
• Low Noise Operation: High-frequency 1.5MHz switching allows for effective filtering and minimal output ripple.
• Plug-and-Play Stability: No adjustment required; simply connect input and output for a stable 5V rail.
