II SMPS control IC
TEA1552
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134); note 1.
Notes
1.
All voltages are measured with respect to ground; positive currents flow into the chip; pin V
CC
may not be current
driven. The voltage ratings are valid provided other ratings are not violated; current ratings are valid provided the
maximum power rating is not violated.
Equivalent to discharging a 100 pF capacitor through a 1.5 k
series resistor.
Equivalent to discharging a 200 pF capacitor through a 0.75
μ
H coil and a 10
resistor.
