MP2321GD-P Monolithic Power Systems

MP2321 19V, 2A, 40A I , High-Efficiency, Q Constant-On-Time, Step-Down Converter in a QFN (2mmx3mm) Package The Future of Analog IC Technology DESCRIPTION FEATURES The MP2321 is a fully-integrated, high- 4V to 19V Operating Input Range efficiency, synchronous, step-down, switch- 2A Output Current mode converter with 40 A of quiescent current. 40 A Quiescent Current The MP2321 achieves 2A of continuous output Output Adjustable from 0.6V current over a wide input supply range with 110m/40m High-Side/Low-Side R DS(ON) excellent load and line regulation and can for Internal Power MOSFETs operate with high efficiency over a wide output Power Good Indicator current load range. The MP2321 is optimized Programmable Soft-Start Time for battery-operated applications and Forced PWM or Auto PFM/PWM Mode applications requiring high light-load efficiency. Selectable With constant-on-time (COT) control, the Programmable Switching Frequency MP2321 provides very fast transient response, Thermal Shutdown easy loop design, and very tight output Short-Circuit Protection: Hiccup Mode regulation. Available in a QFN-14 (2mmx3mm) Package Full protection features include short-circuit APPLICATIONS protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal Tablet PCs shutdown. Solid State Drives The MP2321 requires a minimal number of Gaming readily available, standard, external Battery-Operated Applications components and is available in a space-saving All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
