DM0565R LED DRIVER DOWNLOAD

The collector of an opto-coupler is typically tied to this pin. Supplier Types Trade Assurance. Life support devices or systems are devices or systems which, a are intended for surgical implant into the body, or b support or sustain life, and c whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury of the user. Overload is defined as the load current exceeding a pre-set level due to an unexpected event. This pin is the control ground and the Sense FET source.

The voltage across the resistor is then compared with a preset AOCP level. Donpv philips lcd tv power supply board power supply board pfl CN Zener diode ZD is used for a safety test such as UL.

Therefore, the peak value of the current through the Sense FET is limited. If you are suspect lwd any unauthorized use of your intellectual property rights on this webpage, please report it to us at the following: Temp Current Limit vs. In order to avoid this undesired operation, the over load protection circuit is designed to be activated after a specified time to determine whether it is a transient situation or an dm0556r situation. This causes the feedback voltage to rise.

This event typically happens cm0565r the input dn0565r is increased or the output load is decreased. In this condition, Vfb continues increasing until it reaches 6V, when the switching operation is terminated as shown in figure 7.

We are not responsible for any accidents, delays or other issues caused by the forwarder. Temp ShutDown Delay Current vs.

Comparing the feedback voltage with the voltage across the Rsense resistor plus an offset voltage makes it possible to control the switching duty cycle. After startup, there is no power loss in these resistors since the startup pin is internally disconnected after startup.

The collector of an opto-coupler is typically tied to this pin. When the drain pin and feedback pin are shorted, the zener diode fails and remains short, which causes the fuse F1 blown and prevents explosion of the opto-coupler IC Donpv through the lcd power supply board four light small mouth universal power supply board and easy modification CN The delay time for shutdown is the time required to charge CB from 2.

Relevancy Transaction Level Response Rate. Over load protection t Normal operation Fault situation Normal operation Figure 6.

Gold Plus Supplier The supplier supports Trade Assurance — A free service that protects your orders from payment to delivery. At this point switching stops and the output voltages start to drop at a rate dependent on standby current load. The PWM controller includes integrated fixed frequency oscillator, under voltage lockout, leading edge blanking LEBoptimized gate driver, internal soft start, temperature compensated precise current sources for a loop compensation and self protection circuitry.

This zener diode also increases the immunity against line surge.

Typical Flyback Application Rev. This pin is internally connected to the inverting input of the PWM comparator. The delay time for over load protection is designed to be about 50ms with C of 47nF. In this situation, the protection circuit should be activated in order to protect the SMPS. We have a large stock and the prices are dm0565g sometimes the prices we post are not accurate. If the output consumes beyond this maximum power, the output voltage Vo decreases below the set voltage.

Donpv 46 inch lcd power supply board 4h.

Once the fault condition occurs, switching is terminated and the Sense FET remains off. If the voltage of this pin reaches 6. Temp Operating Freqency vs.
