Description

technical field [0001] The invention relates to a logic control circuit, in particular to a power amplification logic control circuit based on a source follower. Background technique [0002] At present, due to the characteristics of low energy consumption, long service life, safety and environmental protection, LED lamps have become one of the mainstream products for people's living lighting. Since LED lamps are different from traditional incandescent lamps, they need to be driven by a dedicated drive circuit, so there are various protection systems on the market to prevent the drive system from being interfered by internal or external adverse factors. [0003] The logic control circuit is an important control part of the LED lamp protection system, and its running speed and performance stability directly determine the use range and performance of the LED lamp protection system. However, at present, the structures of these logic control circuits are relatively complicated,...
