1. Test conditions: pin 2 and 6 connected to GND, pin 4 and 5 connected to 1.25 V, pin 3 connected to 200 mV.
2. The current depends on the voltage difference between the negative and the positive inputs of the amplifier. If the voltage
on the minus input is 1 mV higher than the positive amplifier, the sinking current at the output OUT will be increased by
Gm *1 mA.

Figure 3. Typical adapter or battery charger application using TSM1014
In the application schematic shown in Figure 3, the TSM1014 is used on the secondary side
of a flyback adapter (or battery charger) to provide an accurate voltage and current control.
The above feedback loop is made with an optocoupler.
