April 17, If not, a new protective burst is initiated. NCP immediately stops the switching pulses and. December 18, 7. Dear sir, I got a power supply usig ic p60 in this resistor burned pin no 8 ie filter to ic pin no 8 pls suggest me the resistor value, what will be the cause it is a benq lcd monitor model w Likes 1 Dislikes datasjeet.

I think your 3 ICs are bad otherwise it must work!! Likes 6 Dislikes 0.
December 28, When the auxiliary winding collapses below UVLOlow. Low Standby Power If SMPS naturally exhibit a good efficiency at nominal load, they begin to be less efficient when the output power demand diminishes. December 29, 4. Depending on the application, the designer can pick up the right device to help reducing magnetics or improve the EMI signature before reaching the kHz starting point.
Figure 15, on the. If yes please do let me know-thanks.
Dagasheet web site, NCP related section. August 19, When I put back the original IC, the power came back! Samsung Phone Charger Repair As a result, the auxiliary voltage also. There have been problems with some suppliers here on different components, like capacitors that are leaky, solid state semiconductors defective.
The auxiliary voltage takes place. As soon as V CC reaches typically 4.
Four different options are available: Posted December 29, 2. Repair Tips Popular Comments. External MOSFET Connection By offering the ability to tailor the level at which the skip cycle takes place, the designer can make sure that the skip operation only occurs at low peak current.
December 18, ddatasheet I installed an IC socket daatasheet test on the other new ICs and the result was the same —totally no power. Posted December 18, 7. In applications where the output current is purposely not.
Likes darasheet Dislikes 0. NCP allows the total standby power to easily reach next. During the startup phase, the peak current is pushed to the.

As a result, cycle skipping can datashet place without having a singing In applications where the output current is purposely not controlled e.
From ic datasheet it seems that the value is more than 4. Instead of skipping cycles at high peak currents, the.
I do not have this monitor with me thus I would not know what will be the value. Posted December 29, 4.
Figure 15, on the following page, portrays the typical operating signals in short circuit. With the mainboard connected the output voltages went up and down but when the mainboard was disconnected it worked perfectly good.
Leave a Reply Cancel reply Your email address will not be published. As a result, the auxiliary voltage also decreases because it also operates in Flyback and thus duplicates the output voltage, providing the leakage inductance between windings is kept low. Marina Likes 0 Datzsheet 0.

Hi if the datasheet state the same information then it could mean that datahseet bought an immitated part i will sugest you buy from a different shop. If the default has gone, then the power supply normally restarts. Have a nice day
