Product Summary
The TPS54286PWPR is a dual output non－synchronous buck converter capable of supporting 2－A output applications that operate from a 4.5－V to 28－V input supply voltage, and require output voltages between 0.8 V and 90% of the input voltage. With internally－determined operating frequency, soft start time, and control loop compensation, The TPS54286PWPR provides many features with a minimum of external components. Channel 1 overcurrent protection is set at 3 A, while Channel 2 overcurrent protection level is selected by connecting a pin to ground, to BP, or left floating. Setting levels of the TPS54286PWPR are used to allow for scaling of external components for applications not needing the full load capability of both outputs.
