MP1584EN Ultra-Small 3A Fixed 9V DC-DC Step-Down Buck Converter

This is the Fixed 9V Edition of the MP1584EN buck converter, a high-frequency step-down regulator designed for reliable, maintenance-free voltage conversion. By utilizing fixed SMD resistors instead of a manual potentiometer, this module eliminates the risk of voltage drift caused by vibration or accidental adjustment, making it ideal for RC drones, robotics, and automotive electronics. It accepts a wide input voltage range and provides a rock-solid 9V output at up to 3A. With its 1.5MHz switching frequency, the module maintains a tiny footprint while delivering up to 96% efficiency with minimal output ripple.

Key Features:

• Fixed 9V Output: Factory-set for precision and stability without the need for manual tuning.
• High-Current 3A Output: Sufficient power for high-drain sensors, microcontrollers, and small motors.
• Industrial Efficiency: Synchronous rectification allows for 92%~96% conversion efficiency.
• Ultra-Small Form Factor: At just 22x17mm, it fits easily into the most compact electronic enclosures.
• High Switching Frequency: 1.5MHz operation allows for smaller inductors and cleaner DC output.
• Advanced Protection: Integrated thermal shutdown and over-current protection for long-term safety.

Package Includes:

1 x MP1584EN Ultra-Small 3A Fixed 9V DC-DC Step-Down Buck Converter
