descriptionThe TPS5120 is a dual channel, high-efficiency synchronous buck controller where the outputs run 180 degrees
out of phase, which lowers the input current ripple, thereby reducing the input capacitance cost. The PWM/SKIP
pin allows the operating mode to switch from PWM mode to skip mode under light load conditions. The skip
mode enables a lower operating frequency and shortens the pulse width to the low-side MOSFET, increasing
the efficiency under light load conditions. These two modes, along with synchronous-rectifier drivers, dead time,
and very low quiescent current, allow power to be conserved and the battery life to be extended under all load
conditions. The 1.5 A (typical) high-side and low-side MOSFET drivers on-chip are designed to drive less
expensive N-channel MOSFET s. The resistorless current protection and fixed high-side driver voltage simplify
the power supply design and reduce the external parts count. Each channel is independent, offering a separate
controller, overcurrent protection, and standby control. Sequencing is flexible and can be tailored by choosing
different softstart capacitor values. Other features, such as undervoltage lockout, power good, overvoltage,
undervoltage, and programmable short-circuit protection promote system reliability.
