Hi,
I am using a LM5116 device and have questions about off-sequence.
Attach the off-sequence waveform.
8V is externally supplied to VCCX.
Since EN is pulled up from VCCX, if the voltage of VCCX drops slowly at the time of OFF, EN does not easily fall below the threshold and the device cannot be turned off.
I am thinking of toggling EN with logic without pulling up from VCCX so that EN can be turned off immediately.
Is it okay to turn off EN abruptly with a logic circuit?
I am worried that this will have a negative effect as there is a zener diode at 6V inside the EN.
The UVLO pin is connected to VIN. Is it OK to turn off UVLO after turning off EN?
