MP1496DJ-LF-Z

MP1496 High-Efficiency, 2A, 16V, 500kHz Synchronous, Step-Down Converter EC R NE O EF W M ER D ME E N TO SI D ED G M N P2 S FO 33 R 2 The Future of Analog IC Technology DESCRIPTION FEATURES The MP1496 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve a 2A continuous output current with excellent load and line regulation over a wide input supply range. The MP1496 has synchronous mode operation for higher efficiency over the output-current–load range. • • • • • • Current-mode operation provides a fast transient response and eases loop stabilization. • • • • • Protective features include over-current protection and thermal shut down and external SS control. The MP1496 requires a minimal number of readily-available standard external components, and is available in a space-saving 8-pin TSOT23 package. Wide 4.5V to 16V Operating Input Range 100mΩ/40mΩ Low-RDS(ON) Internal Power MOSFETs Proprietary Switching-Loss–Reduction Technique High-Efficiency Synchronous Mode Operation Fixed 500kHz Switching Frequency Can Synchronize with a 200kHz-to-2MHz External Clock Externally Programmable Soft-Start OCP Protection and Hiccup Thermal Shutdown Output Adjustable Starting from 0.8V Available in an 8-pin TSOT-23 Package APPLICATIONS • • • • Notebook Computers and I/O Power Digital Set-Top Boxes Flat-Panel Television and Monitors Distributed Power Systems All MPS parts are lead-free and adhere to the RoHS directive.
