TS1051
Constant Voltage and Constant Current Controller
For Battery Chargers and Adaptors
Principle of Operation and Application Hints (continues)
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.
And example of a suitable compensation network is shown in typical application circuit. It consists of a capacitor Cvc1=2.2nF and a
resistor Rcv1=470K
Ω
in series, connected in parallel with another capacitor Cvc2=22pF.
The current control trans-conductance operational amplifier can be fully compensated. Both of its output and negative input are

application circuit. It consists of a capacitor Cic1=2.2nF and resistor Ric1=22K
Ω
in series. When the Vcc voltage reaches 12V it
could be interesting to limit the current coming through the output in the aim to reduce the dissipation of the device and increase the
stability performances of the whole application. An example of suitable Rout value could be 330
Ω
in series with the optocoupler in
case Vcc=12V.
Start Up and Short Circuit Conditions
The TS1051 is not provided with a high enough supply voltage in under start-up or short-circuit conditions. 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 TS1051 has
to be ensured under any condition. It would then be necessary to add some circuitry to supply the chip with separate
power line. This can be achieved in numerous ways, including an additional winding on the transformer. The following
schematic shows how to realize a low-cost power supply for the TS1051 (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 TS1051 supply voltage is 14V, this
low-cost auxiliary power supply can only be used in applications where the regulated line voltage does not exceed 7V.
