Description

The TPS55383 and TPS55386 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 and soft start time, these converters provide many features with a minimum of external components. The outputs of the two error amplifiers are accessible allowing user optimization of the feedback loop under a wide range of output filter characteristics. Channel 1 overcurrent protection is set at 4.5 A, 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 configured to allow either ratiometric or sequential startup sequencing. Additionally, the two outputs may be powered from different sources.
