Integrated Circuit for Realizing Zero Power Consumption Standby, of Switching Power Supply

摘要

An integrated circuit for realizing a zero power consumption standby of switching power supply is disclosed, including a zero-power-consumption controller for controlling the switching power supply. The zero-power-consumption controller comprises a charge coupled circuit, a zero-power-consumption microprocessor, and a zero-power-consumption voltage regulation circuit, and an input from an AC power source is sequentially fed into the zero-power-consumption voltage regulation circuit and the zero-power-consumption microprocessor via the charge coupled circuit.
