MP2326GD-Z

MP2326 The Future of Analog IC Technology 19V, 4A, 40µA IQ, High-Efficiency Constant-On-Time (COT) Step-Down Converter in a 2mmx3mm QFN Package DESCRIPTION The MP2326 is a fully integrated, high-efficiency, synchronous, step-down, switch-mode converter with only a 40μA quiescent current. This very compact device achieves a 4A continuous output current over a wide input-supply range with excellent load and line regulation, and it operates with high efficiency over a wide output current load range. It’s optimized for battery-operated applications and applications requiring high lightload efficiency. With constant-on-time (COT) control, the MP2326 provides very fast transient response, easy loop design, and very tight output regulation. Full protection features include SCP, OCP, UVP, and thermal shutdown. The MP2326 requires a minimal number of readily available, standard, external components with a space saving 2mmx3mm 14-pin QFN package.
