Beschreibung

The MP2119 is an internally compensated 1.5MHz fixed frequency PWM synchronous step-down regulator. MP2119 operates from a 2.7V to 6V input and generates an output voltage as low as 0.8V.The MP2119 integrates a 100mΩ high-side switch and a 100mΩ synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, the MP2119 basedsolution delivers a very compact footprint with a minimum component count.The MP2119 is available in a small 3mm x 3mm QFN package.
