warm when kicking around 3A) How does it work? Well, this converter takes an input voltage between 7V and 24V and steps it down to a fixed 5V output voltage. It uses a constant frequency, current-mode control architecture to provide a stable and reliable power supply for your electronics projects. But that's not all! This power supply module also features over-temperature protection, short circuit protection, and over-current protection, so you can rest assured that your delicate components are safe. The compact size of this board makes it perfect for applications where space is limited. Whether you're building a small robot, a portable device, or a power-hungry project, this little converter can handle it all. So say goodbye to your power supply woes and get your hands on this high-efficiency DC/DC step-down converter today. Your electronic devices will thank you!

Product description

Your power supply problems just got SOLVED! This little circuit board may look tiny but inside is a high efficiency DC/DC step-down converter which can output up to 3 Amp at 5V without the need of any heat-sink or forced cooling. (It does get a bit toasty at 3A though) UBEC stands for "universal battery eliminator circuit" and this UBEC is designed to replace a 5V supply in RC planes and 'copters but its also great for any kind of microcontroller or electronics project that runs off of 5V. We tried a half dozen different 'BECs and found this one to be the best in terms of range and stability. You can check the technical tab for the analysis of input/output range and current draw. To use, connect 5V-16V to the shorter, thicker wires and 5V will be generated on the thinner, longer wires. You'll get 5V (+-5%) regulated output from 6-15VDC input. 3A output current, 5A peak - if you're trying to draw 3A you'll need to give it a little more than 6V though, 7V works well. The UBEC has built in filter capacitors on the input and output, but its a switching supply so its a little noisy compared to a linear regulator. We pulled the heatshrink off of one and found an MP2307 you can check the datasheet for conversion efficiency and other specifications. Here are some numbers we found when attaching various loads to the UBEC:
