Phase Control Circuit - General Purpose Feedback
Description
The integrated circuit U211B2/ B3 is designed as a phase
control circuit in bipolar technology with an internal fre-
quency-voltage converter. Furthermore, it has an internal
control amplifier which means it can be used for speed-
regulated motor applications.
