description
●The 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.
