SN7101 Description

The SN7101 is integrated a high stability band gap voltage reference, two ORed operational amplifiers and a current source. This IC pares 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.
