As soon as the gate-source signal (V GS) goes high to turn on the top side control FET, the body diode turn-off process of the low side FET is initiated. The diode current rolls off at a constant slope (di/dt) to zero and then reverses the direction. The negative current ... WebA “Light Emitting Diode” (LED) is a variant of the standard diode with the same characteristics. The obvious difference is that when current flows through an LED it generates visible (non-visible) light. When looking at the specifications for a LED, there are two key ratings to note: the “Forward Voltage” and the “Forward Current.”. cwe beauty supply
