Teensy 3.1 PWM output @ 5v

[Patrick Harrop]

Hi

My apologies if this has already been answered. Although teensy 3.1 is 5 v tolerant, its output is at 3.3 volts. I am currently using LED buck pucks that require a voltage range of 0 to 5.0 volts from PWM. Any suggestions on how to amplify PWM signals from the teensy (which should have a max of 3.3 volts) to the range of 5 volts? I know this is a rather basic question, but I am a bit of a novice here. Any direction would be appreciated. Thanks

A simple NPN transistor will do.

Simple solution is to go to Sparkfun.com and purchase a uni-directional or bi-directional level shifter.

+1 for simple NPN transistor solution - level shifter isn't a good solution for this imho.

Yeah, the transistor will be cheaper, simpler, smaller and able to carry a larger current.
