TPS7A78: use Pin SDIN of TPS7A7833 as a second DC_Voltage source

Christoph Tutschner

Part Number: TPS7A78

Hello @all

is it possible to use SDIN Pin of TPS7A7833 as a second DC-Voltage source? We want to switch a latched Relay with 12V or 6V for 20mseconds. (Current for 12V Relay:83mA, current for 6V Relay: 170mA)

Do you think this is possible? For 3.3V LDO output we only need 10mA. How do I have to change Cs?

Thanks,

Christoph

Hello Christoph,

I have answered this question in an alternate post (https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1067093/tps7a78-scin-pin-as-voltage-source/3948597#3948597). I will close this thread. Thanks!
