Understanding MOSFET Current Rating in Datasheets

WebWhen the monitored current exceeds the current limit, the comparator output goes high and disables the PWM outputs for the remaining time in the PWM cycle. On the next cycle, if the comparator output is back to zero (i.e. the current is below the limit), the PWM output is enabled again. Webcurrent data with the duty cycle to obtain average phase current will be impaired by a filter time constant, rendering this option ineffective. Since the DC link current does not reveal … bokesoft.comWebFor emulated peak current-mode, the valley current is sampled on the down-slope of the inductor current. This is used as the dc value of current to start the next cycle. bokes creek winery ohio
