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. 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.
180° out-of-phase operation reduces the ripple current through the input capacitor, providing the
benefit of reducing input capacitance, alleviating EMI and increasing capacitor life.
