产品概述
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.
