I would like to use this part number in my design LTC2953-1, but I'm not sure if the -1 it's the right part number.
I'm going to activate 2 DC-DCs with positive EN pin.
Could anyone help me?
The LTC2953-1 EN pin goes high to enable the downstream DC/DC. If your DC/DC converter gets enabled by a HIGH input then the LTC2953-1 is the correct choice.
