DC-DC 12V to 3.3V 5V Multi-output Power Supply Module

DC-DC 12V to 3.3V 5V Multi-output Power Supply Module offers a robust and convenient solution for powering your electronics projects. This compact module efficiently converts a higher input voltage, typically from a 12V adapter or battery, into two of the most common voltage levels required by microcontrollers, sensors, and peripherals: 3.3V and 5V. Engineers and hobbyists rely on this module to simplify power management, eliminate the need for multiple regulators, and ensure a stable, reliable power source for their circuits.

Key Features:

• Dual Voltage Output: Provides a dedicated and simultaneous output for both 3.3V and 5V.
• Wide Input Range: Accepts a broad input voltage from 6V to 12V, accommodating various power sources.
• Efficient Buck Converter: Uses a highly efficient switching regulator design, reducing heat generation and power waste compared to linear regulators.
• High Current Output: Delivers sufficient current for most microcontroller-based projects and sensor arrays.
• Compact PCB Design: The small form factor makes it easy to integrate into a wide range of embedded systems and prototypes.
• Short-Circuit Protection: Built-in safeguards protect the module and connected components from damage.

Datasheet Reference:

• Since this is a generic module, refer to the datasheets of common buck converter ICs like the LM2596 or MP1584 for details on the underlying technology.

Applications:

• Robotics: Powering microcontrollers, servos, and sensors from a single battery source.
• DIY Projects: Supplying stable power to Arduino, Raspberry Pi, ESP32, or other development boards.
• Sensor Networks: Running multiple sensors that require different voltage levels.
• Automotive Electronics: Stepping down a vehicle’s 12V power to operate accessories.

Equivalent Models:

• LM2596 Module: A single-output adjustable buck converter.
• MP1584 Module: A smaller, single-output buck converter with high efficiency.
• 7805/7833 Linear Regulators: Simpler, but less efficient, alternatives that require heat sinks and a more complex setup for multiple outputs.
