MP1496S High-Efficiency, 2A, 16V, 500kHz Synchronous, Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP1496S is a high-frequency, Wide 4.5V to 16V Operating Input Range synchronous, rectified, step-down, switch-mode 150m/70m Low-R Internal Power DS(ON) converter with built-in power MOSFETs. It MOSFETs offers a very compact solution to achieve a 2A Proprietary Switching-LossReduction continuous output current with excellent load Technique and line regulation over a wide input supply High-Efficiency Synchronous Mode range. The MP1496S has synchronous mode Operation operation for higher efficiency over the output- Fixed 500kHz Switching Frequency currentload range. Can Synchronize with a 300kHz-to-2MHz External Clock Current-mode operation provides a fast Externally Programmable Soft-Start transient response and eases loop stabilization. OCP Protection and Hiccup Protective features include over-current Thermal Shutdown protection and thermal shut down and external Output Adjustable Starting from 0.8V SS control. Available in an 8-pin TSOT23 Package The MP1496S requires a minimal number of APPLICATIONS readily-available standard external components, and is available in a space-saving 8-pin Notebook Computers and I/O Power TSOT23 package.
