Ứng dụng VIPer22A thiết bộ nguồn PC
A desktop PC power supply is generally made of two power supplies: the main one built around a forward structure and able to deliver a few hundreds of Watt and switched off in standby mode; the second one with a power capability of up to 15 W always operates to insure the ”instant on” feature or simply the waking up from the off state.
This application note describes the results obtained when designing a VIPer22A in the standby section of such power supplies. A particular concern is the consumption in the idle mode (0.5W of output power),where the input power must not exceed 1W. In addition, a brown-out feature monitors the input voltage inorder to switch off the power supply when it is too low.
