MP2392 High-Efficiency, 2A, 24V, 650kHz Synchronous, Step-Down Converter with PG and Soft Start In SOT583 DESCRIPTION FEATURES The MP2392 is a fully integrated, high- Wide 4.2V to 24V Operating Input Range frequency, synchronous, rectified, step-down, 110m/45m Low R Internal Power DS(ON) switch-mode converter with internal power MOSFETs MOSFETs. The MP2392 offers a very compact 200A Low I Q solution that achieves 2A of continuous output High-Efficiency Synchronous Mode current with excellent load and line regulation Operation over a wide input range. The MP2392 uses Power-Save Mode (PSM) at Light Load synchronous mode operation for higher Fast Load Transient Response efficiency over the output current-load range. 650kHz Switching Frequency Constant-on-time (COT) control operation Programmable Soft-Start Time provides very fast transient response, easy loop Power Good (PG) Indication design, and very tight output regulation. Output Over-Voltage Protection (OVP) Over-Current Protection (OCP) and Hiccup Full protection features include short-circuit Pre-Bias Start-Up protection (SCP), over-current protection (OCP), Thermal Shutdown under-voltage protection (UVP), and thermal Available in a SOT583 (1.6mmx2.1mm) shutdown. Package The MP2392 requires a minimal number of readily available, standard, external APPLICATIONS components and is available in a space-saving Game Consoles SOT583 package.
