I have this DC DC converter and want to understand how it turns on and off.

It says this in the manual how to enable it (ON / OFF ) in the picture below.

My question is, can I put a regular push button (on/off) switch between the enable and Vin- for it to turn on and off?

Thank you

 

I believe so, it says low logic turns the module on.

 

Your push button would need to be the type that stays on when pushed and needs a second push to release.

 

One additional note. You are aware that a mechanical switch will "bounce", or rapidly alternate between "on" and "off" for several tens of milliseconds each time you turn it on or off.

In bench qualifying lotsa converters over the years, I've never seen switch bounce cause a problem - and I've tried. I drive an enable transistor with a function generator, starting at 1 kHz and slowing down until the output wakes up. Usually it takes 50 ms before anything happens. Vicor's bricks are spec'd at something like 100-150 ms.

I didn't say the TS had to do anything about it, just that he should be aware. It is pretty simple to eliminate.
