Description

General part information

TPS54291 Series

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. Channel 1 can provide up to 1.5 A of continuous current. Meanwhile, Channel 2 supports up to 2.5 A.

Current mode control simplifies the compensation. The external compensation adds flexibility for the user to choose different type of output capacitors.
