AP3965/66/71 Operation Description (continued) Thus the output constant current is given by: IpkN N S P OUT …………(9) Leading Edge Blanking (LEB) When the power switch is turned on, a turn-on spike on the output pulse rising edge will occur on the sense -resistor. To avoid false termination of the switching pulse, a typical 500ns leading edge blanking is built in. During this blanking period, the current sense comparator is disabled and the gate driver cannot be switched off. The built-in LEB in AP3965/66/71 has shorter delay time from current sense terminal to output pulse than those IC solutions adopting ex ternal RC filter as LEB. Built-in Cable Compensation The AP3965/66/71 has built-in fixed voltage of 0.35V typical to compensate the drop of output cable when the load is changed from zero to full load. A typical 0.01µF external capacitor connected to the CPC pin is used to smooth voltage signal for cable compensation. Over Temperature Protection The AP3965/66/71 has internal thermal sensing circuit to shut down the PFM driver output when the die temperature reaches +160°C typical. When the die temperature drops about 40°C, the IC will recover automatically to normal operation.
