General Description

The TPS54290, TPS54291, and TPS54292 devices are dual-output, fully synchronous buck converters capable of supporting applications with a minimal number of external components.

It operates from a 4.5-V to 18-V input supply voltage, and supports output voltages as low as 0.8 V and as high as 90% of the input voltage.

Both high-side and low-side MOSFETs are integrated to provide fully synchronous conversion with higher efficiency.
