A feedback voltage of 6V trig- gers over load protection OLP. It also helps to prevent transformer saturation and. T D OFF independent of. It is not until Vcc reaches the UVLO upper threshold 12V that the internal start-up switch opens and de- vice power is supplied via the auxiliary transformer winding. The voltage across the resistor is then compared with datasbeet.

The typical soft start time is 15msec, as shown in figure 8, where progressive increments of Sense FET current are allowed during datasheef start-up phase. Typical continuous power in a non-ven. Frequency Change With Temperature 2. Once the Vcc reaches. When the gate turn-on. In order to prevent this situation, an over voltage protection OVP circuit is employed. Turn Off Delay Time. This device is a basic. Home – IC Supply – Link.

Turn On Delay Time. The Drain pin is designed to connect directly to the primary lead of the trans. Although connected to an auxiliary transform- er winding, current is supplied datasbeet pin 5 Vstr via an internal switch during startup see Internal Block Diagram section. Delay current 5uA charges the Cfb.

In order to avoid undes- ired activation of OVP during normal operation, Vcc should be properly designed to be below 19V. The pulse width to the power switching device is progres- sively increased to establish the correct working conditions for transformers, inductors, and capacitors. At start up the internal datasheett supplies internal bias and charges an external storage capacitor placed between the Vcc pin and ground.

It is not until Vcc reaches the. Sense FET source terminal on primary side and internal control ground. The feedback voltage pin is the non-inverting input to the PWM comparator. Startup Voltage Vstr Breakdown. If the sensing resistor voltage is greater. Minimizing the length of the trace connecting this pin to the transformer will decrease leak- age inductance.

It also helps to prevent transformer saturation and reduce datazheet stress on the secondary diode.

Although connected datasheeet an auxiliary transform. 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.

This device is a basic platform well suited for cost effective designs of flyback converters. In addition to start-up, soft. The pulse width to the power switching device is progres.
