的LM3673降压DC - DC转换器进行了优化,从单节锂离子电池和输入电压轨供电2.7V至5.5V的低电压电路。 它可提供高达350mA的负载电流,在整个输入电压范围。 有几个不同的固定输出电压可供选择,以及范围从1.1V至3.3V的可调输出电压版本。

该器件提供了优越的性能和移动电话和类似的便携式系统的性能。 LM3673采用PWM和PFM之间的智能自动切换,提高效率。 在PWM模式下,器件工作在固定频率为2 MHz(典型值)。 迟滞PFM模式延长电池的使用寿命,减少在轻载和待机状态下的静态电流为16μA(典型值)。 内部同步整流PWM模式操作期间提供高效率。 在关断模式下,设备的关闭,耗电量降低至0.01μA(典型值)。

LM3673是一个微小的5焊球MicroSMD包铅(PB)和无铅(NO PB)的版本。 一个为2 MHz(典型值)的高开关频率允许使用微小的表面贴装元件,电感和两个陶瓷电容。
