MP1492 2A, 4.2V-16V Input, Fast Transient Synchronous Step-down Converter DESCRIPTION O E EF W M M ER D E E N TO SI D ED G M N P1 S FO 47 R 6 The Future of Analog IC Technology FEATURES    The MP1492 is a fully integrated, high– efficiency 2A synchronous rectified step-down converter. The MP1492 operates at high efficiency over a wide output current load range. Adaptive Constant-On-Time (COT) control mode provides fast transient response, eases loop stabilization, and operates with a low-cost electrolytic capacitor.     The MP1492 requires a minimum number of readily available standard external components and is available in an 8-pin SOIC ROHS compliant package.  Wide 4.2V to 16V Operating Input Range 2A Output Current Adaptive COT for Fast Transient Response Low RDS (ON) Internal Power MOSFETs Proprietary Switching Loss Reduction Technique Programmable Switching Frequency OCP, SCP, OVP, UVP Protection and Thermal Shutdown Output Adjustable from 0.805V to 13V APPLICATIONS    Digital Set Top Boxes Flat Panel Television and Monitors Distributed Power Systems EC All MPS parts are lead-free and adhere to the RoHS directive.
