Product Summary

The TPS54283PWPR is a Dual non-synchronous converter. TPS54283PWPR is dual output non-synchronous buck converters capable of supporting 2-A output applications that operate from a 4.5V to 28V input supply voltage, and require output voltage between 0.8V and 90% of the input voltage. With internally-determined operating frequency, soft start time, and control loop compensation, these converters provide many features with a minimum of external components. The applications of the TPS54283PWPR include Set Top Box, Digital TV, Power for DSP and Consumer Electronics.
