Description

PS222S is specially designed for switching power supply system. Four important functions of PS222S are the following: over-voltage protection, over-current protection, under-voltage protection and power good signal generating.

OVP/UVP (Over-Voltage/Under-Voltage Protection) monitors 3.3V, 5V and 12V of PS222S to protect our power supply. FPO/ goes to high when one of these supply voltages exceeds their normal operation voltage range.

OCP (Over Current Protection) of PS222S monitors IS33, IS5, IS12 input current sense. Composed of "Iref" and "protection current range resistor", an adjustable over-current condition helps users design OCP easily.

An additional OCP channel of PS222S helps users monitor another 12V rail output current. Power good signal generating can notify personal computer when power supply is ready or power supply is going to shutdown, therefore it can provide a reliable power supply environment.
