... TOP221-227 TOPSwitch-II Family Functional Description (cont.) Control Voltage Supply CONTROL pin voltage V is the supply or bias voltage for the C controller and driver circuitry. An external bypass capacitor closely connected between the CONTROL and SOURCE pins is required to supply the gate drive current. The total amount of capacitance connected to this pin (C restart timing as well as control loop compensation ...

... The current source is switched on and off with an effective duty cycle of approximately 35%. This duty cycle is determined by the ratio of CONTROL pin charge (I (I and I CD1 CD2 operation when the output MOSFET is switching.

... vary from 100 V to 380 V DC which corresponds to the full universal AC input range. The TOP221 is packaged pin power DIP package. The output voltage ( directly sensed by the Zener diode (VR1) and the optocoupler (U2). The output voltage is determined by the sum of the Zener voltage and the voltage drop across the LED of the optocoupler (the voltage drop across R1 is negligible) ...

... C1 and C6 attenuates differential-mode emission currents caused by the fundamental and harmonics of the trapezoidal or triangular primary current waveform. C5 filters internal MOSFET gate drive charge current spikes on the CONTROL pin, determines the auto-restart frequency, and together with R1 and R3, compensates the control loop.

... TOP221-227 Key Application Considerations General Guidelines • Keep the SOURCE pin length very short. Use a Kelvin connection to the SOURCE pin for the CONTROL pin bypass capacitor. Use single point grounding techniques at the SOURCE pin as shown in Figure 9. • Minimize peak voltage and ringing on the DRAIN voltage at turn-off ...
