Product Description

The TPS54291PWPR 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 to 18V input supply voltage and supports output voltage as low as 0.8V 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 1.5A of continuous current, meanwhile, channel 2 supports up to 2.5A. 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.
