In the first situation with fixed input , you re faced with the same sort of decisions as discussed in 对于输入固定的第一种情况,面临的问题和
The most important point is that it can change work mode between 1x and 1 . 5x at fixed input voltage value to improve led efficiency in the application of led driver 这种根据输入电压选择工作模式的方式,在驱动白光led的应用中,提高了驱动器的led效率。
In the application of driving white led , an auto - adjustable charge pump which adjust work mode according to the forward voltage of load led and input voltage is presented . the conventional charge pump changes work mode at fixed input voltage value 在电荷泵驱动白光led的应用中,本论文研究设计了一种根据负载led正向导通压降和输入电压来选择电荷泵工作模式的电荷泵型led驱动器。
When mne chose an entry mode in the process of progressing , it is the prompt ion of the transactions efficiency of property which made the maximize profit of m & a higher than greenfield investment , that is to say , when the income of the improvement of the transaction efficiency of property is enough to remedy the fixed input of greenfield investment , m & a occurs 当跨国公司在演进过程中选择进入模式时,市场上产权的交易效率提高使得跨国公司选择并购的最大效用高于绿地投资,也就是说当产权交易效率的提高收益足以弥补绿地投资的固定投入时,跨国并购产生。反之则跨国公司选择绿地投资作为最优进入途径。
