across the CSD capacitor will vary from 0V if there is no
load to approximately 5V at maximum load.
This is provided that the correct value of current sense
resistor has been selected for the maximum rated load and
line voltage supply of the convertor. This should be 0.33
Ohm (0.5W) for a 100W system running from a 220-240V
AC line. (It should be noted that the RCS resistor value is
also critical for setting the limits for the shut down circuit)
In RUN mode the oscillator frequency will vary from
approximately 34kHz when VCSD is 5V (maximum load) to
70kHz when VCSD is 0V (no load). The result of this is that
if a lighter load, such as a single 35W lamp, is connected to
a 100W convertor, the frequency will shift upwards so that
the output voltage falls below the maximum that is desirable
for the lamp. This provides sufficient compensation for the
load to ensure that the lamp voltage will always be within
acceptable limits but does not require a complicated regulation
scheme involving feedback from the output.
An additional internal current source has been included to
discharge the external capacitor. This will provide
approximately 10% ripple at twice the line frequency if CSD
is 100nF.
The advantage of this is that during the line voltage half
cycle the oscillator frequency will vary by several kHz thus
spreading the EMI conducted and radiated emissions over
a range of frequencies and avoiding high amplitude peaks
at particular frequencies. In this way the filter components
used may be similar to those used in a common bipolar self-

Figure 6, VS voltage and CSD voltage.
In the above trace it can be seen that a leading edge phase
cut (triac) dimmer is connected at close to maximum
brightness. There is a short delay at the beginning of each
half cycle before the AC line voltage is switched to the
convertor. Dimming increases the ripple in the CSD voltage
and gives more modulation. This is an inherent effect that
causes no system problems.
The startup sequence of the CSD pin can be seen from the
point where VCC increases above the UVLO+ threshold.

This trace shows that after the CSD voltage has ramped up
through soft start, the system switches over to voltage com-
pensation mode and a ripple exists which allows the fre-
quency modulation (or ?dither?) to occur. In this case the
