Principles of Operation and Application Tips

3.3 Compensation
The voltage-control trans-conductance operational amplifier can be fully compensated. Both of its output
and negative input are directly accessible for external compensation components.
An example of a suitable compensation network is shown in Fig.2. It consists of a capacitor Cvc1=2.2nF
and a resistor Rcv1=22K
in series.

3.4 Start-up and short circuit conditions
Under start-up or short-circuit conditions the TSM1015 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 considered not to be precise enough for the application, then a sufficient
supply for the TSM1015 has to be ensured under any condition. It would then be 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.
3.5 Voltage clamp
The following schematic shows how to realize a low-cost power supply for the TSM1015 (with no
additional windings).Please pay attention to the fact that in the particular case presented here, this low-
cost power supply can reach voltages as high as twice the voltage of the regulated line. Since the
Absolute Maximum Rating of the TSM1015 supply voltage is 28V. In the aim to protect he TSM1015
against such how voltage values a internal zener clamp is integrated.
