Abstract

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 7μs 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%.
