Hi,
I would like to use the LMZ14203H to provide a -12 V Vout on a 24 V Vin. On the "Inverting Application for the LMZ14203 SIMPLE SWITCHER Power Module" application report, it shows an example circuit where the EN pin has a voltage divider that supplies 10.5Vin on turn on?
I am not quite understanding what value of Rent I should be choosing for my circuit. The LMZ14203H data sheet says the max voltage into the EN chip should be 6.5V.
Thanks.
This is the Inverting Application sheet: http://www.ti.com/lit/an/snva425a/snva425a.pdf
