My TPS62802 generates +3.3VDC output from a USB +5VDC input. I would like to have the DC/DC converter shut down once its input drops below a certain voltage (let's say ~ +4V), to avoid unexpected operation. Currently, regulation is maintained down to fairly low voltages, so I would like to modify at the EN-pin in order to accomplish this. However, this IC includes a sometimes-present 500k pull-down resistor as part of its "Smart enable" function. And further, this IC appears to be a somewhat "loose EN-pin threshold voltage" class device (non precise EN-pin) so I'm not sure a resistor divider is appropriate - is there a preferred/suggested way to adjust the EN-pin threshold? SVS?
