The SN7101 is integrated a high stability band gap voltage reference, two ORed operational amplifiers and a current source. This IC compares the DC voltage and the current level at the output of a switching power supply to an internal reference.

It provides a feedback through an Opto-coupler to the PWM controller IC in the primary side. The controlled current generator can be used to modify the level of current limitation by offsetting the information coming from the current sensing resistor.

The SN7103 is a monolithic IC that includes one independent op-amp and another op-amp for which the non inverting input is wired to a 2.5V fixed Voltage Reference.
