摘要: | The proposed digital low-dropout regulator uses nonlinear switching control (NLSC) technique to suppress voltage ripple to less than 6mV when the switching noise voltage of a switching regulator operating in a power-saving mode is greater than 50mV. In addition, the NLSC technique improves the current efficiency by reducing the quiescent current to less than 10 A and reduces the switching power loss through variable switching frequency control. With a load step of 1-20mA, the transient response time is 1.3 s and the peak current efficiency is 99.8 at heavy loads. |
