Use a Kelvin connection to the SOURCE pin for the CONTROL
pin bypass capacitor as shown in Figure 9.
Minimize peak voltage and ringing on the DRAIN voltage at
turn-off. Use a Zener or TVS Zener diode to clamp the DRAIN
voltage.
Under some conditions, externally provided bias or supply
current driven into the CONTROL pin can hold the
TOPSwitch
in one of the 8 auto-restart cycles indefinitely and prevent
starting. Shorting the CONTROL pin to the SOURCE pin will
reset the
TOPSwitch
. To avoid this problem when doing bench
evaluations, it is recommended that the V
power supply be
turned on before the DRAIN voltage is applied.
Key Application Considerations
CONTROL pin currents during auto-restart operation are much
lower at low input voltages (< 20 V) which increases the auto-
restart cycle period (see the I
C
vs. Drain Voltage Characteristic
curve).
Short interruptions of AC power may cause
TOPSwitch
to enter
the 8-count auto-restart cycle before starting again. This is
because the input energy storage capacitors are not completely
discharged and the CONTROL pin capacitance has not
discharged below the internal power-up reset voltage (V
C(RESET)
).
In some cases, minimum loading may be necessary to keep a
lightly loaded or unloaded output voltage within the desired
range due to the minimum ON-time.
For additional applications information regarding the
TOPSwitch
family, refer to AN-14 in the 1996-97 Data Book and Design
Guide or on our Web site.
