Description

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.
