STWBC86 coil driver rise and fall time
Hello, is there any way to adjust the rise and fall time of the coil driver on the STWBC86? The observed rise and fall times are currently 3-4ns, but I am looking for ways to extend them to 70ns+ due to excessive emissions with my product.Thank you!
Resolved! droput voltage for LDL1117
I just bought 10 pcs of LDL1117S33R which i plan to use them to power 3.3V modules form a 4V regulated source.According to the data sheet the typical dropout is 350mV and max is 600mV @1.2A. My module consumes less than 500mA, so i expect to have eno...
