Hi,
I'm using an LM2663 as a simple inverter, represented as the first application schematic in the datasheet.
In this case, we're simply inverting +5V to -5V.
We need to defeat the LM2663 during power-up, but doing so seems to cause latch-up.
If the shut-down pin is exerted at power-up, the LM2663 doesn't ever start. Exerting the shut-down pin AFTER power-up, results in shutdown.
How can I prevent latching at power-up for the simple inverting application ?
Thanks,
