Compact Design
Miniature size ensures ease of integration into space-constrained projects, providing a practical power solution without sacrificing performance or increasing footprint.
Multiple Units
Pack of five modules delivers excellent value, enabling users to tackle multiple projects or repairs simultaneously, ensuring users have reliable power solutions on hand.
Product Details
- Wide voltage compatibility applies to 4.5V - 24V input (compatible with 5V/9V/12V/24V power supplies), stably outputting 3.3V. It can supply power to microcontrollers, sensors, etc., with a maximum current of up to 1.8A.
- Compact and Space - Saving with Ultra - Small Size: 17.5×12×4.5 mm. Easily fit into the narrow spaces of DIY, embedded or portable projects.
- Stable power supply with low ripple (< 30mV) and a switching frequency of 1MHz - 1.5MHz. It keeps the power supply clean and protects devices from voltage fluctuations.
- Load Protection Instructions For motors/servos (inductive loads), a diode and a capacitor must be added to prevent damage.
- 5-Pack Great Value: Includes 5 Modules Ideal for hobbyists/makers to build multiple circuits or expand projects.

Customer Questions & Answers
-
Question:
What is a 3.3V Buck Converter Module used for?
Answer: The 3.3V Buck Converter Module is designed to step down voltage from a higher DC input (4.5-24V) to a stable 3.3V output. This makes it ideal for powering microcontrollers, sensors, and other electronic devices that require 3.3V. For example, if you have a device that operates on 3.3V and you only have a 9V battery, this module efficiently converts the voltage, ensuring safe and reliable operation. -
Question:
How does the DC-DC converter maintain output stability?
Answer: This buck converter employs a switching regulator design that adjusts the output voltage in response to load changes. By maintaining high efficiency with low heat generation, the module ensures stable 3.3V output even when the input voltage fluctuates. This is especially beneficial in projects where stable voltage is crucial, such as in robotics or IoT applications. -
Question:
Can I use this module with solar panels?
Answer: Yes, you can use the 3.3V Buck Converter Module with solar panels. If your solar panel outputs between 4.5 and 24V, this module can effectively convert that to 3.3V, making it suitable for powering low-voltage devices like weather stations or sensors. Just ensure your solar panel's output matches the input requirements to achieve optimal performance. -
Question:
What are the efficiency ratings for this buck converter?
Answer: The 3.3V Buck Converter Module boasts high efficiency, typically around 85% to 95%, depending on specific load conditions. This level of efficiency is critical in battery-operated devices as it prolongs usage time and reduces energy waste. For instance, in portable electronic devices, higher efficiency directly translates to longer battery life. -
Question:
What is the maximum current output of the module?
Answer: The maximum current output of the 3.3V Buck Converter Module is generally within the range of 2A to 3A. This makes it suitable for small to moderate loads, such as powering multiple sensors or a microcontroller along with associated peripherals. When designing your circuit, ensure that your load does not exceed this current capacity to avoid damage to the module. -
Question:
Is this module suitable for breadboard prototyping?
Answer: Absolutely! The 3.3V Buck Converter Module is compact and designed to work seamlessly with breadboards for prototyping. Its small form factor allows for easy integration into various electronic projects, making it perfect for students or hobbyists who want to test different configurations without soldering components permanently. -
Question:
Can I use this buck converter for higher voltage applications?
Answer: While the 3.3V Buck Converter Module is specifically designed to output 3.3V, it can handle input voltages between 4.5V and 24V. If you need a different output voltage, you would need a different converter designed for those specifications. For applications requiring multiple voltage outputs, consider using different modules for each voltage requirement. -
Question:
What kind of protection does this module provide?
Answer: This module typically includes over-current and thermal protection features to safeguard both the converter and the connected devices. Such protections ensure that under adverse conditions, like excessive current or heat, the module shuts down or limits output to prevent damage. This makes it particularly reliable for sustained use in critical applications. -
Question:
Where can I buy the 5pcs 3.3V Buck Converter Module in Malta?
Answer: You can purchase the 5pcs 3.3V Buck Converter Module from Ubuy in Malta. Ubuy offers a wide range of electronic components, ensuring that you get quality products delivered right to your door.
