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). When power
supply is in short circuit, the supply voltages will be much smaller than their normal
operation voltages .We can use UVP to monitor our power supply whether it is in the
dangerous power load.
Power good signal generating notifies personal computer when power supply is
ready or power supply is going to shutdown, therefore it can provide a reliable power
supply environment.
