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
MOSFETs. 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.
