Four important functions of PS236 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 13V 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) monitors IS33, IS5, IS13 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 helps users monitor additional VSX 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.
