1. 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 3.5 mA.

Figure 3. Typical adapter application using TSM1011
In the application schematic shown in Figure 3, the TSM1011 is used on the secondary side
of a flyback adapter (or battery charger) to provide accurate control of the voltage and
current. The above feedback loop is made with an optocoupler.
