Hi,
Yes, you can leave PWRGD floating if you are not using it.
I would also recommend the newer, smaller, cheaper TPS62827A or TPS62865 instead.
Thanks,
Chris
Hi Mitchell,
When Vin is tied to EN, the device will turn off due to UVLO instead of the EN going low. The D/S says that UVLO will turn on the discharge circuit. It will be weaker, however, due to the lower Vin applied to the device.
Newer 4A devices…
