Low Power Standby Circuit with Micom Power Control

摘要

The present invention relates to a low-power standby circuit of the microcomputer power supply control system for reducing the power consumption of the standby power supply, especially in the standby state of the home appliance.;In the standby circuit, the DC voltage is supplied to both the microcomputer and the preamplifier in the standby state, resulting in a large power consumption problem of the standby power source. Most of the standby power is consumed by the microcomputer and a very small amount of power is consumed in the preamplifier.;Therefore, in order to solve the above problems, the present invention configures the microcomputer power control unit to cut off the power supply of the microcomputer, which is the main power consumption source in the standby state, and to supply power only to the preamplifier, thereby reducing power consumption of the standby power supply. Its main purpose is to minimize it.
