Overload Operation Four different options are available: August 19, May 9, Hi Marina, Yes you right.
There have been problems with some suppliers here on different components, like capacitors that are leaky, solid state semiconductors defective.
With the mainboard connected the output voltages went up and down but when ddatasheet mainboard was disconnected it worked perfectly good.
I do not have this monitor with me thus I would not know what will be the value.
P60 Datasheet –
Datasheer installed an IC socket to test on the other new ICs and the result was the same —totally no power. Skip cycle offers a proven mean to reduce the standby power. When the auxiliary winding collapses below UVLOlow.
Hi Jackson, Good to hear from you again. I beging to believe that both IC’s are not really similar. Bradley Brake September 28, at 4: NCP immediately stops the switching pulses and. Jestine Yong March 31, at HI Jayesh, I do not have this monitor with me thus I would not know what will be the value. December 18, If the default has gone, then the power supply normally restarts.
Jestine Yong September 28, at 8: The power supply is thus operated in burst mode and avoids any lethal thermal runaway. Posted December 29, 2. Hi Chad, It is great to hear from you again. When this happens, NCP immediately stops the switching pulses and unbias all unnecessary logical blocks.
Figure 15, on the following page, portrays the typical operating signals in short circuit. By offering the ability to tailor the level at which the skip.
As soon as V CC reaches typically 4. Hi Parthiban, Thanks and wishing you Happy N By the 12003p60 you have a very cool photo!
April 17, December 14, The reason I install the IC socket so that the circuit track will not break from excessive soldering and desoldering of the ICs being tested. If not, a new protective burst is initiated. Dear sir, I got a power datashert 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 0 Dislikes 0.
When I put back the original IC, the power came back! Expected IC arrival will be next week. Posted December 18, 7. Have a nice day Your email address will not be published. I will find out when I got the new batch of IC. If not, a new protective burst is initiated, shielding the SMPS from any runaway. Semiconductor web site, NCP related section.

September 5, 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. During the startup phase, the peak current is pushed to the.
And the same monitor benq datsaheet power board. December 29, 4.
Repairing Computer Motherboard I got a good blog post by Ranotosh on The overall consumption drops, while keeping the gate grounded, and the V CC slowly falls down.
Marina Likes 0 Dislikes 0. I think your 3 ICs are bad otherwise it must work!! I had the same problem like Dimon. As a result, cycle skipping can take place without having a singing In applications where the output current is purposely not controlled e. Instead of skipping cycles at high peak currents, the.
