Functional Description
Start Up Behaviour (Pin 14)
When power is applied to the chip and the voltage
V
14 at Pin 14 (VCC) is less than the
upper threshold (
V
ON) of the Supply Voltage Comparator (SVC), input current I14 will be
less than 100
µA. The chip is not active and driver output (Pin 13) and control output
(Pin 4) will be actively held low. When
V
14 exceeds the upper SVC threshold (VON) the
chip starts working and
I
14 increases. When V14 falls below the lower SVC threshold
(
V
OFF) the chip starts again at his initial condition. Figure 4 shows the start-up circuit and
Figure 5 shows the voltage
V
14 during start up. Charging of C14 is done by resistor R2 of
the “Primary Current Simulation” (see later) and the internal diode D1, so no additional
start up resistor is needed. The capacitor
C
14 delivers the supply current until the
auxiliary winding of the transformer supplies the chip with current through the external
diode D14.
It is recommended to switch a small RF snubber capacitor of e.g. 100 nF parallel to the
electrolytic capacitor at pin 14 as shown in the application circuits in Figures 15, 16, and
17.
