SMPS control IC with
synchronization function
TEA1541

In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured with respect to
ground (pin 2); positive currents flow into the chip; pin 1 is not allowed to be current driven. The voltage ratings are valid
provided other ratings are not being violated; current ratings are valid provided the maximum power rating is not
violated.
