I am using the TPS65053 in a design but have no need for DCDC1. How should the L1 and FB_DCDC1 pins be connected if DCDC1 is not used?
Note, VINDCDC1/2 must be connected to to the same potential as VCC.
If a DCDC converter is not used, the enable pin, EN_DCDC#, must be connected to ground; the inductor can be omitted and the pin, L#, should be floated. FB_DCDC# should be connected to ground as well.
Thanks, Daniel!
