24V-12V 9V to 5V Fixed Output,3A Power Step-Down Adjustable Module-Chip is MP1584EN?

This DC-DC Buck Converter Module based on the MP1584EN chip is a compact and efficient step-down power supply module that converts a wide input voltage range (typically 4.5V to 28V) to a stable 5V DC output. It is capable of delivering up to 3A continuous output current with high efficiency (>90% under typical loads).

The module is suitable for powering 5V logic devices, microcontrollers (like Arduino, ESP32), sensors, and other peripherals from higher-voltage sources such as 24V industrial supplies, 12V battery packs, or 9V adapters. It features over-temperature, over-current, and short-circuit protection, making it safe and robust for embedded and industrial applications.
