The Sense FET and the con. It datashet a 0. The Drain datashest is designed to connect directly to the primary lead of the trans- former and is capable of switching a maximum of V. Maximum practical continuous power in an open frame. Then, Vfb climbs up in a similar manner to the over load situation, forc- ing the preset maximum current to be supplied to the SMPS until the over load protection is activated.

Once the Vcc reaches. In order to prevent this situation, an over voltage protection OVP circuit is employed.

This device is an integrated. Frequency Change With Temperature 2. 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 dl0165g conditions. It also datashete to prevent transformer saturation and.

The voltage on the output capacitors is progressively increased with the intention of smoothly establishing the required output volt- age. Internal Soft Start Time. 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. Because excess energy is provided to the output, the output voltage may exceed the rated voltage before the over load protection is activated, resulting in the breakdown of the devices in dl0165e secondary side.

In order to prevent this situation, an over. Vcc instead of directly monitoring the output voltage. Although connected to an auxiliary transform- er winding, current is supplied from pin 5 Vstr via an internal switch during startup see Internal Block Diagram section. Pin Configuration Top View 3.

In order to avoid undes- ired activation of OVP during normal operation, Datashedt should be properly designed to be below 19V. Startup Voltage Vstr Breakdown.

If this pin is tied to Vcc or left floating, the typical current limit will be 1. In addition to start-up, soft- start is also activated at each restart attempt during auto- restart and when restarting after latch mode is activated.
