I'm not sure if this is the right place to ask this kind of question(mine seems practical as opposed to academic) but here it goes.
The embedded board I am using(Jetson TX1) can be powered using:
- 4S LiPO(4 cell / 14.8V nominal / 16.8V charged) with 1-2A (or 15W) of
- 3S LiPO (11.1V nominal / 12.6 charged / 9V discharged) with 1-2A (or 15W) of continuous current
I'm trying to mount Jetson TX1 on my quadrocopter which has XT30/XT60 ports with the following spec:
- Output Voltage: 20 - 26.1 V
- Max Continuous Output Current: 10 A
Now I'm trying to buy a DC-DC step down converter and I'm currently looking at DROK 200143 DC-DC Buck Converter 3.5-30V to 0.8-29V 10A Step-down Volt Adjustable Output Regulator Module Power Supply which has
- 3.5-30V input
- 0.8-29V output output
- 10A Max output current
My concern is the input current. The output current only needs to be 2A but it should take 10A input current.
Is the max input current same as the max output current?
