This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The TPS54383 and TPS54386 are dual output, nonsynchronous 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
