TPS56C230: EN signal

Simon Mali1

Part Number: TPS56C230

How is it with Enable signal for this converter (pin 12) ? Is 5V enabled and 0V disabled? Not connected means enabled, I guess? What is the trigger level?

Hi Simon,

The EN threshold is listed on datasheet page 5. It means that typically when Ven is larger than 1.3V, part will be enabled. While when Ven is lower than 1.1V, part will be disabled. There are process and part variation here.

And we can see that there is Enable internal pull down current which is 2uA. So if EN is floating, part is disabled.
