正向压降 meaning in English

forward voltage drop

The forward voltage drop in the on - state is only a few volts ( typically 1 to 3 v depending on the device blocking voltage rating )
在导通状态的正向压降很小（取决于阻断电压的值，一般为1 ~ 3伏）。
With forward voltage of white led lower and lower , the efficiency of traditional charge pump driver is lower and lower , too . the new auto - adjustable charge pump can keep the charge pump working in high efficient 1x mode as long as possible
根据负载led的正向压降和输入电压选择工作模式,可以让驱动器最大限度地工作在高效率的1x模式下,有效地提高了驱动器的led效率。
The sample with low emitter efficiency has completed as the method of above . this lead to the greatly decrease of the reverse recovery time and the low reverse leakage and forward voltage , especially the excellent temperature character of the leakage . the test date shows that the samples reach the first class of international level
