MP2109 详细介绍

MP2109双路独立的1.5MHZ恒定频率、电流模脉宽调制(PWM)架构的降压型变换器。每一路变换器都集成了一个主开关管和同步整流管以提高效率,无需外部肖特基二极管。MP2109是单节锂电池供电应用的理想选择。当输入电压范围在2.5V~5.5V时,每路变换器可以提供800mA的电流,输出电压可调节低至0.6V。MP2109可以在100%的占空比下低压降工作。

MP2109 】Dual 1.2MHz, 800mA Synchronous Step-Down Converter. Adjusted Output Voltage (0.6V to 6V).
 
The MP2109 contains two independent 1.2MHz constant frequency, current mode, PWM step down converters. MP2109 Each converter integrates a main switch and a synchronous rectifier for high efficiency without an external Schottky diode. The MP2109 is ideal for powering portable equipment that runs from a single cell Lithium-Ion (Li+) battery. Each converter can supply 800mA of load current from a 2.5V to 6V input voltage. The output voltage can be regulated as low as 0.6V. The MP2109 can also run at 100% duty cycle for low dropout applications.
