When using a lithium battery pack of more than 3S, a switch? mode BEC has much higher efficiency with lower heat. For a traditional linear BEC, For example, a 4S lithium battery pack has a typical voltage of 14.8V, to let BEC output 5V/1A, the current flow into the BEC is at least 1A, so the power on BEC is 14.8V* 1A=14.8W. But useful output power is only 5V*1A=5W, so the efficiency of the linear mode BEC is
just 5W/14.8W=33.8%, the redundant power 14.8W?5W=9.8W changes to heat, which makes the BEC very hot, and makes it enter a protection state, thus unable to work
Features:
Provide large output current
Overcurrent and overheat protection function
The max efficiency of the chip is up to 93%
The small size and the light weight make it very convenient to use
Shows the working status with an indicator(LED)
