Open Loop Phase Control Circuit
U208B
Description
The integrated circuit, U208B, is designed as a phase con-
trol circuit in bipolar technology with internal
supply-voltage monitoring. As the voltage is built up, un-
controlled output pulses are avoided by internal
monitoring. Furthermore, it has internal-current and volt-
age synchronisation. It is recommended as a low cost
open-loop control.

General Hints and Explanation of Terms
To ensure safe and trouble–free operation, the following
points should be taken into consideration when circuits
are being constructed or in the design of printed circuit
boards.

p/2 p 3/2p 2p
D The connecting lines from C2 to Pin 5 and Pin 1 should
be as short as possible, and the connection to Pin 1
should not carry any additional high current such as
e.g. the load current.
D When selecting C2, a low temperature coefficient is
desirable.
