When the switch is closed, the inductor current increases linearly to its peak value. When the switch opens, the inductor current linearly decreases to zero. At this point, the drain voltage of the switch ( essentially floating d ...

Therefore, the output capacitor must “absorb” the difference between the delivered power and the power consumed by the load. This means that when the power fed to the load is lower than the demand, the output ...

To prevent negative voltages on the ZCD pin, the pin is internally clamped to V (600 mV typ) when the CL(NEG) ZCD winding is negative. Similarly, the ZCD pin is clamped to V (5.7 V typical), when the voltage rises ...
