SIR I WANT TO MAKE SMPS WITH OUT PUT OF 1) +5V 4A FOR CMOC CUIRCIT 2) +12V 2A FOR 7 SEG DISPLAY 3) +18V 3A FOR DC MOTOR 4) +48V 3A FOR SOLONOID IS IT POSSIBLE TO MAKE WITH "PI" IC? IF YES, WHICH IC? IS IT POSSIBLE TO

hello, could you arrange to display the download of PI xls 6.0 until version 7.0 is completely through. It is because, with every design Xls is reporting few bugs as discussed till now. It is making design unreliable & doubt-full to proceed ahead for design. So pls provide PI xls

Hello, We have designed a SMPS based on TNY switch III - TNY277. Universal Input, 14v DC o/p @ 0.5 Amps, TL431 based feed back. EE-16 core transformer. We have observed that, when no output diode is present and SMPS is powered up, then, TNY277 gets damaged. After replacing with

Hi PI engineer, I must do a project that has 100-377VAC input and output is 3W. I want to use power integration chips. Can I use your chips with external mosfet. If possible please send me a referance circuit(tny275 possible). Thanks,

Hi PI Engineer, How can I calculate my power supply efficiency. I designed a power supply with tny275pn. Input 85-265VAC and 2 outputs 12V/0.25A and 5V/0.25A. Thanks,

Hi, I am little weak in power supply design. But I am attempting to do as it seems all the things are made easy by PI. I am making 15VA power supply with 5V/2A 26V/0.2V output. But I could not see any information about bleeder resistance at output and NTC

In version v6.5 there was the option to restrict the transformer choice to sizes commonly available for Europe etc. In this case the software just picked cores from the E-Series (e.g. EPCOS). I understand that I can now manually do the same thing with the component sets, but these libraries

Hello, I´m using TNY279G for a flyback AC/DC, with two outputs: 5V to 1A and 24V to 0,7A. The problem is that the exit of 24V is not stabilized. If R106 is not mount and there is no load in the outputs, the 5V output ripple is very low and

when using PIXls designer for a three output flyback (6v@.3A, 18v@.1A, and -18@.1A--negative output on 3rd output) the result indicates using 1 turn for the -18 in both the transformer parameters and transformer construction. Even when I change the 3rd output to +18, the result still gives 1 turn. Is

as per my observation, i found, when we run spread sheet xls, if .xls shows transformer primary winding 20T, then when we see transformer diagram, it shows 22T or lets say if we see 20T for biasing in xls, you will observe 21T in transformer diagram for the same. is
