Additional Infomation About Product

MP2119 2A, 6V Synchronous Step-Down Switching Regulator The Future of Analog IC Technology DESCRIPTION FEATURES 2A Output Current The MP2119 is an internally compensated Input Operation Range: 2.7V to 6V 1.5MHz fixed frequency PWM synchronous step-down regulator. MP2119 operates from a All Ceramic Capacitor Design 2.7V to 6V input and generates an output 1.5MHz Fixed Switching Frequency voltage as low as 0.8V. Adjustable Output from 0.8V to 0.9xV IN Internal Soft-Start The MP2119 integrates a 100m high-side Frequency Synchronization Input switch and a 100m synchronous rectifier for Power Good Output high efficiency without an external Schottky Thermal Shutdown diode. With peak current mode control and Cycle-by-Cycle Current Limiting internal compensation, the MP2119 based Hiccup Short Circuit Protection solution delivers a very compact footprint with a minimum component count. 3mm x 3mm QFN Package The MP2119 is available in a small 3mm x 3mm APPLICATIONS QFN package.
