(2) Timer-Latch Short Circuit Protection Circuit (SCP)
This circuit detects the output voltage level from the error amplifier. When the error amplifier output voltage exceeds
approximately 2.1V, a timer circuit is activated and charges the external capacitor at the CSCP terminal (pin 22). If
the error amplifier output does not return to normal range before the capacitor voltage reaches approximately 0.7V,
a latch circuit is activated and sets both the main and synchronous rectifier side output pins to “L” level. After the
short protection circuit has been activated, it is reset by simply restarting the power supply. (See “METHOD OF
SETTING TIME CONSTANT FOR TIMER LATCH SHORT-CIRCUIT PROTECTION CIRCUIT”.)
