The 4A Adjustable Buck-Boost Module is a versatile power solution that combines high current capacity with automatic voltage regulation. Most converters only work in one direction, but this module can take a low voltage and step it up, or a high voltage and step it down to your exact desired setting. With a 4A current limit, it is significantly more robust than the common XL6009, making it suitable for driving high-power LEDs, charging battery packs, or powering Raspberry Pi setups in automotive environments.
True Auto Buck-Boost: Whether the input is 5V, 12V, or 24V, you can set a constant output of 12V and it will never budge.
4A High Current: Optimized for high-load applications with improved thermal management compared to smaller modules.
Low Ripple & High Efficiency: Uses synchronous rectification technology to minimize energy loss and heat generation.
Large Heat Dissipation: Typically comes with a larger inductor and high-quality capacitors to handle sustained power delivery.
Safe for Electronics: Features under-voltage protection and over-current safeguards.
