High Efficiency, 20 A, Monolithic Silent Switcher 2 Regulator for SoC and Microprocessor Applications

Power budgets continually rise for advanced SoC  solutions used in industrial and automotive systems. Each successive SoC generation adds power hungry devices and increases data processing speed. These devices require reliable power, including 0.8 V for cores, 1.2 V, and 1.1 V for DDR3 and LPDDR4, and 5 V, 3.3 V, and 1.8 V for peripheral and auxiliary components.  Advanced SoC solutions require higher performance than traditional PWM controllers and MOSFETs can provide.  The solutions necessary must be more compact, with higher current capability, higher efficiency, and, more importantly, superior EMI performance.
