MP1653 Datasheet | Monolithic Power Systems

AVNET USE ONLY / DO NOT DISTRIBUTE The Future of Analog IC Technology DESCRIPTION The MP1653 is a fully integrated, highfrequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very pact solution that achieves 3A of continuous output current with excellent load and line regulation over a wide input range. The MP1653 has synchronous mode operation for higher efficiency over the output current load range. Constant-on-time control operation provides very fast transient response, easy loop design, and very tight output regulation. Full protection Features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown. The MP1653 requires a minimal number of readily available, standard, external ponents and is available in a space-saving SOT563 (1.6mmх1.6mm) package. TYPICAL APPLICATION 17V, 3A, 800k Hz, High-Efficiency, Synchronous, Step-Down Converter with Internal MOSFETs Features - Wide 4.2V to 17V Operating Input Range - 70mΩ/40mΩ Low RDS(ON) Internal Power MOSFETs - 200µA Low IQ - High-Efficiency Synchronous Mode Operation - Power-Save Mode at Light Load - Fast Load Transient Response - 800k Hz Switching Frequency - Internal Soft Start - Over-Current Protection (OCP) and Hiccup - Thermal Shutdown - Output Adjustable from 0.8V - Available in a SOT563 (1.6mmх1.6mm) Package APPLICATIONS - Security Cameras - Digital Set-Top Boxes - Flat-Panel Televisions and Monitors - General Purposes All MPS parts are lead-free, halogen-free, and adhere to the Ro HS directive.
