#12662: Step-Up Step-Down Buck Boost Converter (3.5V-28V to 1V-25V)


The Step-Up Step-Down Buck Boost Converter is a versatile and efficient power module that provides voltage regulation in both step-up and step-down modes. It is an essential component in various applications, especially where the power source fluctuates significantly, such as with solar panels. Here are some key features and benefits of this converter:

  1. Wide Input and Output Range: The converter can accept input voltages from 3.5V to 28V, making it compatible with a wide range of power sources. It can output voltages in the range of 1.25V to 26V, providing flexibility for different applications.

  2. High Conversion Efficiency: The module boasts an impressive conversion efficiency of up to 94%. This means that it can effectively convert the input voltage to the desired output voltage with minimal power loss, ensuring optimal energy utilization.

  3. Dual-Stage Operation: The converter works in two stages, starting with a boost stage to increase the voltage to a minimum of 5V and up to 25V. Then, the second stage allows you to set the output voltage between 1V to 25V using a potentiometer. This dual-stage operation enables precise voltage control.

  4. High Output Current Capability: The converter is rated at 1A for continuous operation and can handle short bursts of up to 3A with the use of a heatsink. This makes it suitable for powering a wide range of electronic devices and circuits.

  5. Low No-Load Current: The module has a low no-load current of less than 18mA, which helps in conserving power and reducing energy wastage.

  6. High Switching Frequency: With a switching frequency of 400KHz, the converter can efficiently regulate the output voltage while minimizing output ripple and noise.

  7. Excellent Load and Voltage Regulation: The converter provides tight load and voltage regulation, with load regulation and voltage regulation both within ±0.5%. This ensures stable and consistent output voltage even under varying load conditions.

  8. Compact and Durable Design: The converter has a compact form factor with dimensions of 48mm * 25mm * 14mm, making it easy to integrate into various projects. Its operating temperature range of -40°C to +85°C ensures reliable performance even in challenging environments.

Overall, the Step-Up Step-Down Buck Boost Converter is a reliable and versatile power module that excels in voltage regulation for a wide range of applications. Whether you need to boost, buck, or regulate voltage, this converter offers efficiency, precision, and stability, making it a valuable tool for electronics enthusiasts and professionals alike.
