The Future of Analog IC Technology MP2321 19V, 2A, 40µA IQ, High-Efficiency, Constant-On-Time, Step-Down Converter in a QFN (2mmx3mm) Package DESCRIPTION The MP2321 is a fully-integrated, highefficiency, synchronous, step-down, switchmode converter with 40μA of quiescent current. The MP2321 achieves 2A of continuous output current over a wide input supply range with excellent load and line regulation and can operate with high efficiency over a wide output current load range. The MP2321 is optimized for battery-operated applications and applications requiring high light-load efficiency. With constant-on-time (COT) control, the MP2321 provides very fast transient response, easy loop design, and very tight output regulation.
