Hi,
Wanting to use TPS65320 for the following purposes::
Buck converter supply for 1.2V for uP core, about 1A
LDO supply of standby voltage for uP RAM, max 2 mA over temp, about 4V.
After consulting datasheet and this forum I plan to connect as follows:
VIN to constant battery, KL30 ( with protective measures taken ).
EN2 to VIN to enable LDO.
VIN_LDO and EN1 to 5V supply from another voltage regulator that is switched on when ignition key is turned.
Have I got it right?
What is max current flow can I expect into EN2 when held at 12V ( over temp )?
What is the current on FB2? Or rather what is the maximum resistor values in the feedback net, +-10% error on the output voltage is OK.
Thanks,
Mats
