A feedback voltage of 6V trig- gers over datqsheet protection OLP. Delay current 5uA charges the Cfb. The integrated PWM controller features include: 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. Turn Off Delay Time. It also helps to prevent transformer saturation and reduce the stress on the secondary diode. It also helps to prevent transformer saturation and.
Drain to Source Peak Current Limit. Pin to adjust the current limit of the Sense FET.
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. Turn On Delay Time. It is not until Vcc reaches the.
Vcc instead of directly monitoring the output voltage. If the sensing resistor voltage is greater.
If this pin is tied to Vcc or left floating, the typical current limit will be 1. Positive supply voltage input. The pulse width to the power switching device is progres- sively increased to establish the correct working conditions for transformers, inductors, and capacitors.

Maximum practical continuous power in an open frame. Startup Voltage Vstr Breakdown. 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. 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.

This device is a basic. A feedback voltage of 6V trig. 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. This device is a basic platform well suited for cost effective designs of flyback converters. In addition to start-up, soft. The feedback voltage pin is the non-inverting input to the PWM comparator.
