数字电源 A Versatile Monolithic Digital PWM Controller Don Alfano, Silicon Laboratories I. Introduction offer excellent die area efficiency. The integrated MCU Digital control promises significant system performance makes the controller very flexible and enables user gains resulting from complex control algorithms that are firmware to precisely set and modify system attributes difficult to implement in analog [1,2,7,12]. Digital (i.e. frequency compensation and system protection) and control has reduced susceptibility to component enhance system performance using low-frequency control ……
