8.10 OverVoltage Protection (OVP)
8.12 Input characteristics of complete power-plug
8.11 Output characteristics of complete power-plug
Overvoltage protection can be achieved in the application by pulling pin REG above its
normal operation level. The current primary stroke is terminated immediately, and no new
primary stroke is started until the voltage on pin REG drops to its normal operation level.
Pin REG has an internal clamp. The current feed into this pin must be limited.

Output power: A wide range of output power levels can be handled by choosing the
R
Accuracy: The accuracy of the complete converter, functioning as a voltage source
with primary sensing, is approximately 8 % (mainly dependent on the transformer
coupling). The accuracy with secondary sensing is defined by the accuracy of the
external components. For safety requirements in case of optocoupler feedback loss,
the primary sensing remains active when an overvoltage circuit is connected.
Efficiency: An efficiency of 75 % at maximum output power can be achieved for a
complete converter designed for universal mains.
Ripple: A minimum ripple is obtained in a system designed for a maximum duty factor
of 50 % under normal operating conditions, and a minimized dead time. The
magnitude of the ripple in the output voltage is determined by the frequency and duty
factor of the converter, the output current level and the value and ESR of the output
capacitor.
The input voltage range comprises the universal AC mains (80 V to 276 V)
DS(on)
and package of the TEA152x family. Power levels up to 30 W can be realized.
