Mini MP1584EN DC-DC BUCK Adjustable Step Down Module

The MP1564 module is a high-efficiency step-down (buck) voltage regulator designed to convert a higher input voltage into a stable, lower output voltage. It is commonly used in various electronics and power supply applications due to its efficiency and compact design. Here’s a more detailed description, features, and specifications of the MP1564 module.

MP1564 Module Overview:

The MP1564 is based on a high-efficiency synchronous buck converter. It is a versatile, compact, and efficient solution for stepping down voltage in various applications where space and efficiency are crucial. The regulator can operate over a wide input voltage range and deliver a stable output voltage.

Key Features:

1. Wide Input Voltage Range:

   • 4.5V to 28V, which makes it suitable for use with a variety of input voltages (such as 5V, 12V, 24V systems, or even from battery sources).

2. Adjustable Output Voltage:

   • The output voltage is typically adjustable in the range of 0.8V to 20V (depending on the version and components used).
   • This feature allows you to set the output voltage to a precise value required for your application.

3. High Output Current:

   • Can provide a maximum output current of up to 3A (depending on the version of the MP1564). This is suitable for powering many types of devices, including microcontrollers, sensors, and other electronics.

4. High Efficiency:

   • The module can achieve an efficiency of up to 90% or higher, depending on the input voltage, output voltage, and load conditions. High efficiency reduces power losses and heat generation, which is important in battery-powered applications.

5. Low Quiescent Current:

   • Typically, the MP1564 has a low quiescent current, making it suitable for battery-powered projects where minimizing current draw is critical.

6. Protection Features:

   • Overcurrent Protection: Automatically shuts down or reduces the output current to prevent damage from excessive load conditions.
   • Thermal Shutdown: Protects the module from overheating, ensuring safe operation under high power conditions.
   • Short Circuit Protection: Protects the circuit in case of a short circuit on the output side.

7. Compact Size:

   • The MP1564 is typically available in a small module form factor (often a compact PCB size), which is easy to integrate into space-constrained designs.

8. Adjustable Output Voltage with Feedback:

   • The module typically has a feedback loop, allowing for precise voltage regulation by adjusting the feedback resistors (or using a potentiometer in some cases).

9. Synchronous Rectification:

   • The MP1564 uses synchronous rectification, which improves efficiency by reducing losses associated with diode rectifiers, providing a more efficient energy conversion process.

Specifications:

• Input Voltage Range:

  • 4.5V to 28V (depending on the specific model and configuration).

• Output Voltage Range:

  • Typically 0.8V to 20V (adjustable based on user requirements).

• Output Current:

  • Up to 3A (depending on input voltage, output voltage, and thermal conditions).

• Efficiency:

  • Up to 90% or higher, depending on input/output conditions.

• Switching Frequency:

  • Typically operates around 1.2 MHz, which allows for smaller passive components (inductors and capacitors).

• Overcurrent Protection:

  • Limits the current to prevent damage from overload conditions.

• Thermal Shutdown:

  • Automatically shuts down the regulator if it exceeds safe operating temperatures.

• Short Circuit Protection:

  • Protects against short circuits on the output side.

• Operating Temperature Range:

  • Typically -40°C to 125°C for industrial applications (depending on specific components and configuration).

• Package Type:

  • Often available as a compact PCB module with input and output terminals for easy integration into projects.

Typical Applications:

• Battery-Powered Devices: Used in portable electronics to convert the battery voltage to a stable lower voltage for powering other components.
• Arduino & Microcontroller Projects: Provides regulated power to microcontrollers and sensors from a higher voltage source.
• Power Supplies: Suitable for powering devices requiring a stable voltage, like sensors, LEDs, and low-power circuits.
• Automotive and Industrial Applications: Can be used to regulate power in automotive systems or industrial environments with higher input voltages.

How It Works:

• The MP1564 uses a buck converter architecture to step down the input voltage. It employs a high-frequency switching transistor and a diode or synchronous MOSFET to transfer energy to an inductor, which stores energy temporarily and then releases it to the output.
• The voltage is regulated by adjusting the duty cycle of the switching transistor based on feedback from the output.
