MP1476GTF-P Monolithic Power Systems

MP1476 18V, 2A, 800kHz, High-Efficiency, Synchronous, Step-Down Converter in SOT563 Package DESCRIPTION FEATURES The MP1476 is a fully integrated, high- Wide 4.2V to 18V Operating Input Range frequency, synchronous, rectified, step-down, 126m/58m Low R Internal Power DS(ON) switch-mode converter with internal power MOSFETs MOSFETs. The MP1476 offers a very compact 190A 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 MP1476 uses Power-Save Mode (PSM) at Light Load synchronous mode operation for higher Fast Load Transient Response efficiency over the output current-load range. 800kHz Switching Frequency Constant-on-time (COT) control operation Internal Soft Start (SS) provides very fast transient response, easy loop Over-Current Protection (OCP) and Hiccup design, and very tight output regulation. Thermal Shutdown Output Adjustable from 0.8V Full protection features include short-circuit Available in a SOT563 Package protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal APPLICATIONS shutdown. Security Cameras The MP1476 requires a minimal number of Digital Set-Top Boxes readily available, standard, external Flat-Panel Televisions and Monitors components and is available in a space-saving General Purposes SOT563 package. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under Quality Assurance.
