TPS5120 Datasheet - Texas Instruments

TPS5120 Two-Phase Synchronous Buck DC/DC Controller

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 l.
