摘要：

A voltage-mode Buck converter with a novel Pseudo-Type III compensation is presented. It maintains the fast load transient response, as confirmed by the measured loop gain, and 7 mu s settling time for 500mA load current step. It also transforms the Type III compensator into a summation of an area- and power-efficient error amplifier plus a low-power band-pass filter. Consequently, the area and power consumption of proposed compensator is reduced by 80% and 85%.
