Description
The TPS54383PWPR ,TPS54383 and TPS54386 are dual output, non-synchronous buck converters capable of supporting3-A output applications that operate from a 4.5-V to28-V input supply voltage, and require outputvoltages between 0.8 V and 90% of the input voltage.
With an internally-determined operating frequency.soft-start time, and control loop compensation, theseconverters provide many features with a minimum ofexternal components. Channel 1overcurrentprotection is set at 4.5 A, while Channel 2 overcurrentprotection level is selected by connecting a pin toground, to BP, or left floating. The setting levels areused to allow for scaling of external components forapplications that do not need the full load capability ofboth outputs.
