Tel：886-3-5645656 Fax：886-3-5645626 PS113 PS113 3-Channel Secondary Monitoring IC General Description PS113 is specially designed for switching power supply system. Three important functions of PS113 are the following: over-voltage protection, short circuit protection and power good signal generating. OVP (Over Voltage Protection) monitors 5V, 12V and 3.3V to protect our power supply and PC, when one of these supply voltages exceeds their normal operation voltage. Short circuit protection is done by UVP (Under Voltage Protection).
