EiceDRIVERs: Infineon's 1EDN7550 and 1EDN8550 solve ground-shift issues in SMPS
17.09.2018 · News
Every time a power MOSFET is switched on or off in a switched-mode power supply, parasitic inductances cause ground shifts. This can lead to uncontrolled switching of gate driver ICs...
Circuit converts pulse width to voltage
13.09.2018 · Circuits
The circuit converts pulse information to a clean dc voltage by the end of a single incoming pulse. In another technique, an RC filter can convert a PWM signal to an averaged dc voltage, but this method is slow in responding. Converting low-duty-cycle pulse information is slower yet...
