SK10E116 Datasheet In the absence ofa feedback signal (such as at startup, or a short circuit) the drain current ramp, sensed across R5 and noise filtered by R4/C5 appears on pin l. When the ramp voltage on C5 exceeds the 0.73 V reference signal, the FBK/OCP comparator changes state, shutting down the oscillator and turning offthe MOSFET. Thus the voltage on CSS is held high (6.5 V) by the comparator. When the comparator changes state, CSS discharges via rss; the voltage on CSS ramps down until it reaches 3.7 V. The oscillator turns on the MOSFET. This ramp-down time is internally trimmed t0 50 ccs. The comparator changes state again and the cycle repeats. Thus in the absence of feedback, the current-sense resistor R5 accurately controls the MOSFET maximum current. SK10E116 Price
