  • Product Description
  • -The UBEC is an advanced switching regulator, provides over-current and over-heat protection function, and the witching frequency is 300KHz.The max efficiency of this chip is 92%
    -The smallest size and the lightest weight.

    -Don’t worry about the polarity of battery pack, if the polarity is not correct, the UBEC can’t work, but it will not be destroyed. What you need to do is just swap the battery pack polarity.

    -A shield covers almost all the electronic components on PCB, and a ferrite ring is attached with the output wires to decrease the electromagnetic interference.

    -Compare linear BEC with switch-mode BEC: When using a lithium battery pack more than 3s, a switch-mode BEC has much higher efficiency than linear BEC.

    -For a traditional linear BEC: For example，a 4s lithium battery pack has a typical voltage of 14.8V, in order to let BEC outputs 5V/1A, the current flow into BEC is at least 1A, so the power on BEC is 14.8V* 1A=14.8W. But the useful output power is only 5V*1A=5W, so the efficiency of BEC is 5W/14.8W=33.8%, the redundant power 14.8W-5W=9.8W changes to heat, which makes the BEC very hot.

    -For a switch-mode BEC: In the above case, in order to let BEC outputs 5V/1A, the current flow into BEC is only 0.38A (actual test data), so the power on BEC is 14.8V* 0.38A=5.6W, and the efficiency of BEC is 5W/5.6W=89.3%..
