Description
The TDA 16822 is a current mode pulse width
modulator with built in CoolMOS™ transistor. It fulfils
the requirement of minimum external control circuitry for
a flyback application.
Current mode control means that the current through
the CoolMOS™ transistor is compared with a reference
signal derived from the output voltage of the flyback
application. The result of that comparision determines
the on-time of the CoolMOS™ transistor. The accuracy
of the switching frequency is highly sophisticated due to
temperature compensation. Furthermore overload and
open loop protection is implemented by sensing the
feedback line. This means in case of overload or open
loop the IC is working in protection mode.

2 Electrical Characteristics
2.1 Absolute Maximum Ratings
Note:
Absolute maximum ratings are defined as ratings, which when being exceeded may lead to destruction
of the integrated circuit. For the same reason make sure, that any capacitor that will be connected to pin 7
(
VCC
) is discharged before assembling the application circuit.
