Preliminary specification
Control circuit for a Self-Oscillating
Power Supply (SOPS)
TDA8385
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
All voltages are measured with respect to ground; positive current flow into the IC; all pins not mentioned in the voltage
list are not allowed to be voltage driven. The voltage ratings are valid provided other ratings are not violated; current
ratings are valid provided the power rating is not violated.
