SOP-8
SN7101/P
Voltage and Current Controller
Description
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.
