Abstract

This paper presents a novel fast transient suppression technique to improve the transient response of dc-dc converters with minimal area overhead and power dissipation. The proposed pseudo error voltage technique is implemented in AMS 0.35μm high-voltage CMOS process for wide supply range automotive dc-dc converter. For 18 V to 3.3 V conversion, the proposed technique suppress overshoot voltage from 560 mV to 250 mV and undershoot voltage from 420 mV to 210 mV with 55.3% and 50% improvement respectively for a load transient of 2.8A. This method makes it possible to use very small output capacitance in the buck converter.
