| Abstract: 5.1V zener diode is used to limit the voltage at the Vdd pin. A diode may be put in series with the zener to compensate for the extra Vbe drop if the linear supply configuration is used (Figure 4(b). , including resistor dividers or series resistors with a zener diode shunt (Figure 7). The former is , extends the driver output to beyond the transformer reset, thereby reducing MOSFET body diode conduction , great advantage in reducing body diode conduction and boosting converter efficiency.

| offset voltage is the DC offset bias + 2V F of the IN4148 diodes. NOTE also that as the DC offset control IC's are all provided with an internal V CC zener clamp at about 15.6 VDC so the actual C T effect. In terms of temperature stability, the two diodes in the offset circuit tend to reduce compensated by rectifying the lamp current waveform with a similar diode which tends to increase the DC www.datasheetarchive.com/files/international-rectifier/docs/wcd00010/wcd01032.htm |
