I am a field application engineer at Shanghai Nanxin Semiconductor Technology Co., Ltd. and one of the planners of t...
I would like to ask, for example, the energy metering chip ADE7755, its voltage sampling and current sampling are both converted into small signals through a transformer (such as 220V/10mA) in the for...
Optical communication applications often need to boost the +3.3V input power supply to obtain a set of positive and negative voltages, such as +/-20V. The common practice is to use two chips to genera...
