This device is an integrated high voltage power switching regulator which combine an avalanche rugged Sense FET with a dl065r mode PWM control block. The integrated PWM datawheet features include: This device is a basic platform well suited for cost effective designs of flyback converters. Over load protection 4. The voltage across the resistor is then compared with a preset AOCP level.

In case of malfunc- tion in the secondary side feedback circuit, or feedback loop open caused by a defect of solder, the current through the opto-coupler transistor becomes almost zero. 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.

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 the secondary side.


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

In order to avoid undes- ired activation of OVP during normal operation, Vcc should be properly designed to be below datasyeet. 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.

The pulse width to the power switching device is progres- sively increased to establish the correct working conditions for transformers, inductors, and capacitors. The voltage on the output capacitors is progressively increased with the intention of ddatasheet establishing the required output volt- age. It also helps to prevent transformer saturation and reduce the stress on the secondary diode.

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.
