Any difference between a level converter and a buck dc-dc step-down converter?

I have some of these "5V to 3.3V DC-DC Step-Down Power Supply Buck Module AMS1117 LDO 800MA" lying around.

What I currently want to do is connect a 16x2 LCD with an I2C backpack to my raspi. I've read online that level converters are required to protect the pi's GPIO's.

Are these buck converters cutting it? Or is there some Amp fuckery I'm missing on?
