TPS55386PWP

DC/DC CONTROL, NON-SYNC, 16HTSSOP.

The TPS55386PWP is a dual output non-synchronous Buck Converter capable of supporting 3A output applications that operate from a 4.5 to 28V input supply voltage and require output voltages between 0.8V and 90% of the input voltage. With an internally-determined operating frequency and soft start time, it provides many features with a minimum of external components. The outputs of the two error amplifiers are accessible allowing user optimization of the feedback loop under a wide range of output filter characteristics. Channel 1 overcurrent protection is set at 4.5A, while channel 2 overcurrent protection level is selected by connecting a pin to ground, to BP or left floating. The setting levels are used to allow for scaling of external components for applications that do not need the full load capability of both outputs. The outputs may be enabled independently or configured to allow either ratiometric or sequential startup sequencing.
