There is a time delay datasheeet charging. Pin to adjust the current limit of the Sense FET. The integrated PWM controller features. At start up the internal switch supplies internal bias and charges an external storage capacitor placed between the Vcc pin and ground. The Drain pin is designed to connect directly to the primary lead of the trans- former and is capable of switching a maximum of V.

Sense FET source terminal on primary side and internal control ground. There is a time delay while charging between 3V and 6V using an internal 5uA current source, which prevents false triggering under transient conditions but still allows the protection mechanism to operate under true datashest conditions. In order to prevent this situation, an over.

The voltage across the resistor is then compared with a. The typical soft start time is 15msec, as shown in figure 8, where progressive increments of Sense FET current are allowed during the start-up phase.
