文章主要介绍通过在待机电源输出端增加一个动态负载,而此动态负载是受控于电视待机MCU或者电视待机CPU.即通过人为的增加输出负载电流来达到增加反馈电流,从而增加待机电源的带载能力,提高待机电源输出VCC的稳定性,以达到提高电源主电路的稳定性,解决LED电视在满足低功耗要求下能稳定工作。
The article mainly introduces a dynamic load by adding a dynamic load to the standby power output, and this dynamic load is controlled by the TV standby MCU or TV standby CPU, which increases the feedback current by artificially increasing the output load current, thereby increasing the standby power supply band Load capacity, improve the stability of the standby power output VCC, in order to improve the stability of the main circuit of the power supply, and solve the problem that the LED TV can work stably under the requirement of low power consumption.
