摘要
A low standby consumption power supply system having multi-channels for power supply is used to power first and second circuit blocks. The main supply module provides power to the first circuit-block, while the second supply module provides power to the second circuit-block. The enabling line is used to transmit an enabling signal to the main supply module to switch the main supply module from a power-off status to a power-on status. The enabling line operates under enabling mode and power-off mode. Under enabling mode, the enabling line transmit the enabling signal to the main supply module, such that the main supply module and the low-current supply module respectively provide power to the first circuit-block and the second circuit-block simultaneously. Under the power-off mode, the enabling signal is cut off and the main supply module stop providing power, so as to cut off standby current of the main supply module.
