COMPENSATION
The voltage-control transconductance operational
amplifier can be fully compensated. Both its
output and negative input are directly accessible
for external compensation components.
An example of a suitable compensation network is
shown in
Figure 5. It consists of a capacitor
Ccv1=2.2nF and a resistor Rcv1=22K in series.

START UP AND SHORT CIRCUIT CONDITIONS
Under start-up or short-circuit conditions the
TSM1011 is not provided with a high enough
supply voltage. This is due to the fact that the chip
has its power supply line in common with the
power supply line of the system.
Therefore, the current limitation can only be
ensured by the primary PWM module, which
should be chosen accordingly.
If the primary current limitation is not considered
to be precise enough for the application, then a
sufficient supply for the TSM1011 has to be
ensured under all conditions. This means that it is
necessary to add some circuitry to supply the chip
with a separate power line. This can be achieved
in numerous ways, including an additional winding
on the transformer.
