CONTROL IC HAVING AUTO RECOVERY CIRCUIT, AUTO RECOVERY CIRCUIT OF CONTROL IC, POWER CONVERTER SYSTEM AND METHOD FOR AUTO RECOVERING CONTROL IC
The present invention relates to a control IC, an auto recovery circuit, a power converter system and a method for an auto recovering. In one embodiment, there is proposed to a control IC including: an abnormal state detection unit; a protection unit changing into a protection mode in an abnormal state and changing the protection mode into an operation mode by receiving an auto recovery signal; an IC power unit receiving the power from an input power when an IC power drops until a preset low voltage under the protection mode, blocking a power supply from the input power when the IC power reaches a preset high voltage and repeating a power supplying and blocking; and an auto restart unit counting clocks alternatively repeating a power supply signal and a supply block signal and supplying the auto recovery signal when the number of counts reaches a preset value.
