DESCRIPTION
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.
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.
