Hi, folks So I have two identical half bridge smps, each uses two mosfets and one IR2110 which drives the mosftets, both IR2110 are powered from a single small transformer and rectifier/voltage regulator. Both IR2110 are driven from an SG3525AN oscillator. Now heres the funny thing, when I made the first half bridge and put in the first IR2110 to drive the two mosfets of that half bridge it worked fine, now I installed the other two mosfets in the other half bridge which has a separate transformer, I inserted the second IR2110 which is also driven from the same SG3525 from which the first one gets its signal, but now when I attempt to drive both only one of them works, the other one doesnt work at all. Sekirei season 3 episode 1. In other words the second half bridge i finished later works but the first one doesnt, and quite frankly because the first IR2110 is not driving the mosftets but its not dead or anything when i change the two IR2110 places they both work but only one at a time. I have attached the schematic for my smps, the schematic shows only one full half bridge but my layout for each half bridge is exactly like in the schematic only that both IR2110 are driven from a single power supply and from the same SG3525 chip.

Need comments and sugestion for my projects SG3525 Push-Pull converter inputs DC24V and DC320V with 25/30A outputs. SG3525 is used extensively in DC-DC converters, DC-AC inverters, home UPS systems, solar inverters, power supplies, battery chargers and numerous other applications.

Ok, heres a question, i checked everything twice and to be honest the driving cirucit is not that complicated since most of it is inside the IC's there is nothing wrong but everytime i try to run them together they just dont, one IR2110 works fine while the other one doesnt work, when i measure the output from the IR2110 to the mosfet gates it's the output of one of the IR2110 high side gate drive that is very low, about 0.17 volts while all the other ones are at about 6.5, this is done when the mosfets have no voltage across their D-S. But then I thought maybe, i could either run 4 mosfets, two in pairs parallel from one IR2110, or maybe as I have done in the attached schematic, since i have two separate transformers just get some really high current mosfets and use two to drive both transformers, what do you guys think?
