Monolithic Power Systems MP1498

Description

The MP1498 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in internal power MOSFETs. It offers avery compact solution to achieve 2A continuous output current with excellent load and line regulation over a wide input supply range. TheMP1498 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, thermal shutdown, and external SS control.The MP1498 requires a minimal number of readily-available external components and is available in a space-saving 8-pin TSOT23 package.
