MINI560 DC 5V 5A Step-Down Stabilized Buck Converter Module

MINI560 DC 5V 5A Step-Down Stabilized Buck Converter Module is a high-density synchronous step-down (buck) voltage regulator that converts a 7.0V to 20V DC input into a fixed, precision-stabilized 5.0V DC output at up to 5A peak current. Utilizing synchronous rectification MOSFETs and a shielded molded alloy inductor at 500kHz, it achieves up to 99% peak efficiency in a compact 30mm × 18mm × 5.4mm form factor—making it a premier 5V BEC and embedded power supply for Raspberry Pi, robotics servos, and FPV drones.

Key Features:

• Fixed 5.0V 5A Stabilized Output: Precision fixed-resistor feedback network locks output at 5.0V DC without fragile mechanical potentiometers that can shift under vibration.
• Up to 99% Synchronous Efficiency: Synchronous MOSFET switching delivers 3.5A–4A continuously (5A peak) with minimal thermal rise compared to LM2596 or XL4015 boards.
• Ultra-Low Output Ripple (<30mVp-p): 500kHz switching frequency with high-capacity X7R MLCC ceramic capacitors ensures clean power for single-board computers and HD cameras.
• Logic-Level Enable (EN) Pin: Allows remote ON/OFF control of the 5V 5A output rail from any 3.3V/5V GPIO pin.
• Ultra-Light 5.5g Footprint: Slim 30mm × 18mm profile mounts flat inside drone frames, robot chassis, and handheld instruments.
