DescriptionThe TPS54290, TPS54291, and TPS54292 devices
are dual-output, fully synchronous buck converters
capableof supporting applications witha minimal
numberof external components.It operates from
4.5-V to 18-V input supply voltage, and supports
output voltagesas lowas 0.8V andas highas 90% the input voltage.
Both high-side and low-side MOSFETs are integrated provide fully synchronous conversion with higher
efficiency. Channel1 can provide up to 1.5A
continuous current. Meanwhile, Channel2 supportsto 2.5A.
Current mode control simplifies the compensation.
The external compensation adds flexibility for
userto choose different typeof output capacitors.
180° out-of-phase operation reduces the ripple
current through the input capacitor, providing
benefitof reducing input capacitance, alleviating EMI
and increasing capacitor life.
