TPS54386PWPG4

IC, DUAL BUCK CONVERTER 600 KHZ.

The TPS54386PWPG4 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, 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 4.5A, 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 may be configured to allow either ratio-metric or sequential startup sequencing. Additionally, the two outputs may be powered from different sources.
