Posted on April 26, 2016 at 13:07Hi to all,please help!!I made a DC-DC converter from 9-30V input and 5V output. You can find in the attachment a pdf print from the eDesign Suite.The Cin that I'm using is: C1210C335K5RACTUThe L is: B82477G4153MThe C...
Posted on April 25, 2016 at 08:45Hi all, We are using VIPer12A in our Flyback isolated SMPS. The circuit starts at minimum 20Vrms. There is no information about the minimum Vrms value that the IC starts. The datasheet says IC starts working Vddon wh...
Posted on April 24, 2016 at 10:36Hi New to this forum, Sorry if I have posted this in the wrong place. Is it possible to use fold back current limit on a L200 regulator ? Is there an example circuit that I can look at ? Thanks Steve Clarke #l200
Posted on April 21, 2016 at 22:26Hello, I am testing the L5491 Evaluation board and having problems getting the IGBTs to turn on. Currently I am using FGH60N60 IGBTs for controlling a light bulb. I have a microcontroller generating a 1kHz 5Vpp squa...
Posted on April 20, 2016 at 14:06Hi,I'm new bee here. My project needs to consume very less power. I see that STM32L053R8 consumes 88µA/MHZ that means it takes 88µA*16 for 16MHZ? or is it different?. I would like to perate my controller at 5MHZ only...
Posted on April 18, 2016 at 21:49Hello, EVAL6480H uses very robust MOSFETs with hefty intrinsic diodes (25A pulsed current). Does this suggest that it would be ok in practice to exclude catch/snubber diodes from H-bridge design when employing the L6...
Posted on March 17, 2016 at 11:26Dear all,we are noticing breakdown of SPV1040 in our implementation on a board for energy harvesting from solar panel. The breakdown is only for some board. Here you can see the configuration.The solar panel is a cou...
