A High Efficiency Green Mode Switch Mode Power Supply Regulator
一种高效率绿色模式开关电源控制器的研究

A novel green mode switch mode power supply(SMPS)buck regulator with an on-chip power switch is proposed.By adopting PWM/Burst multi-mode operation,its conversion efficiency is enhanced over the entire load range.It reduces the light-load and standby power dissipation of modern portable products powered by batteries,which results in prolonging their standby time and battery lifetime.Moreover,a seamless transition is successfully realized by over voltage suppression.In addition,an on-chip current sensing tec...
