Edition A13, 05/99
Typical Application
Remarks:
1)
2)
3)
4)
To provide low frequency stability C2 should be 10 times C3.
Be aware that also coupling capacitors determine the switching times.
The collector current at Q1 can be estimated by Ic=0.6V / Rx[
W
].
Place C2 as close to the device as possible.
