sg3525 ic advice for inverter

Apr 30, 2008 2 Replies

Hi All, I'm trying to use a sg3525 ic in a Sinewave PWM. I've looked everywhere and can't find a straight answer, so I hope that someone here with experience can assist.



Question 1: How can I configure (if at all) this device so that given the input, a SPWM signal, in one clock cycle it will turn on MOSFET Driver Out A for SPWM(high), and MOSFER Driver Out B for SPWM(low)(with dead time to ensures both devices don't conduct at the same time).



Question 2: Is there another device that might do this, that also ensures both devices don't conduct at the same time. (Dead time)



Thanks in advance,



Nathan

,They use switchers in car amplifer SMPS's all the time...I seem to recall a couple discussions about adjusting the dead-time on a '3525. IIRC,you can set/adjust dead time by adding a resistor.. (but don't quote me on that)
