Product Summary

The PIC627 is a Microsemi ESP Switching Regulator. The PIC627 is designed, constructed and specified for use in high current switching regulator applications. The designer of the PIC627 is thus relieved of one of the most time consuming, tedious and critical aspects of switching regulator design: choosing the appropriate switching transistors and commutating diode and empirically determining the optimum drive and bias conditions.
