TPS54290/1/2 is a dual output fully synchronous buck converter 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. Channel1 can provide up to 1.5 A of continuous current, meanwhile, Channel2 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.
