Posted on June 29, 2010 at 13:06 i have designed a AC-DC converter by using viper22a. the topology is fly-back. as the viper22a's datasheet say, the Vds(st) should be less than 400V. so i want to know if the viper22a may be damaged when the input AC voltage is 300V ? at that time,Vds(st) would be 424V (300*sqrt(2)). it has excessed the maximum Vds(st). what on earth does the Vds(st) mean?       at last ,i am sorry for my poor english. please sb give me a definitive answers. thanks. #viperplus #viperplus

Posted on June 10, 2010 at 13:52One of our client facing following problems.                 They want to use the LED7707 for Solar Lantern application.  their output will be 3Nos of 1W LED string for which they need constant current output of 150mA. But their Board is not working.  1. They  shorted the Rows with connecting wires by soldering.  Will this affect the IC?2. The output is  connected to V boost and GND.3.What to do with SW1 and SW2?They  want it to work with a 6VBattery.That is they will be giving a input voltage from 4.5V to about 7.5V.The circuit that they  want to build up is attached . Pls Reply ASAP.

Posted on April 29, 2010 at 10:45Hi, My name is Alex IVASCU and I am working as a design engineer for a Romanian - Italian company - ANTRICE - OMICRON Industriale, involved in AC-DC SMPS rectifiers manufacturing. I designed a power 3kW PFC as an input stage using a Boost topology. At the moment I am using a 16Arms - IDT16S60C SiC diode from Infineon. This value is related to the fact that the rectifier should also operate at 180Vrms AC input. I saw that ST is also involved in manufacturing SiC diodes. I would like to know if and when ST will be able to offer a similar 16Arms diode to have a second supplier? Until now my company manufactured 5k SMPS rectifiers where we used Infineon diode and we have a forecast of cca.3k more units. I am very interested to have information regarding the above mentioned issue. Best regards, Alex
