The TPS54386-Q1 are dual-output, non-synchronous buck converters capable of supporting 3-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 an internally-determined operating frequency, soft-start time, and control-loop compensation, these converters provide many features with a minimum of external components. Channel-1 overcurrent protection is set at 4.5 A, whereas the 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 may be configured to allow either ratiometric or sequential start-up sequencing. Additionally, the two outputs may be powered from different sources.
