Which electronic component to use to step down voltage from 7.4v lipo battery to varying output voltage between 3v - 6v? Answered

Hi all,

I dont have much knowledge of electronic components and I am trying to make a robot. I have servos with operating voltage of 6v and I will be connecting it with a battery. I am not able to figure it out which electronic component should I use to step down the voltage from 7.4v lipo battery to have varying output between 3v-6v with maximum output current of 2amp.

Thank you in advance for your advice :)

Thank you for the reply. My other concern is I will be using wireless transmission between arduino using Zigbee module so the device what you suggested has coil on it which will hamper the signal transmission between arduino. I am planning to use LM317T, what do you think on this ?

If, as you admit, you have little knowledge of electronics, take advice when it is given. Yonatan is quite correct. That device is an excellent choice. An LM317 will burn a lot of power for no reason.

Easiest solution would be to buy one of those buck converter boards on amazon. Most/all of them use (in some cases knockoffs) the very popular LM2596 simple switcher chip.
