Preliminary specication
Power plug for the universal mains
TEA1401T
OUTPUT CHARACTERISTICS OF COMPLETE
POWER PLUG
Output power
Maximum switching frequency is approximately 150 kHz.
Internal MOS maximum switch current is 0.5 to 1 A.
Maximum handled power with universal mains is
approximately 10 W.
Accuracy of current regulation
The accuracy of the IC itself is
±5%. Accuracy of the
complete converter is approximately
±7%, depending on
the transformer and other components.
Accuracy of voltage regulation
The voltage loop inside the IC has an accuracy of
±4%.
Accuracy of the complete converter is approximately
±7%.
Voltage overshoot
When voltage overshoot is detected (during the secondary
stroke), the IC first has to wait until this stroke is finished in
the normal way. After that the power level of the converter
is set to the minimum level within one cycle.
Voltage overshoot is triggered at 20% above nominal
output voltage. If at the moment that overshoot is detected,
the transformer still contains energy; this energy can
cause some further increase of the output voltage.
In case of a pre-load resistor across the output,
the converter keeps the output voltage under static
conditions on its nominal value. Voltage overshoot will only
be a dynamic phenomenon in this situation. When only a
Zener diode is applied, the Zener voltage will appear at the
output continuously under no-load conditions.
Efciency
An efficiency of 72 to 75% at maximum output power can
be achieved for a complete 8 W converter designed for
universal mains.
Ripple
The magnitude of the ripple in output voltage is determined
by the duty cycle of the converter, the output current level
and the value and Electrical Series Resistance (ESR) of
the output capacitor.
A minimal ripple is obtained in a system designed on a
maximum duty cycle of 50% under normal operating
conditions and a minimized dead time.
Ripple is inversely proportional to input and output
voltages.
INPUT CHARACTERISTICS OF COMPLETE
POWER PLUG
Input voltage
The input voltage range comprises the universal AC-mains
(90 to 280 V). The input transient voltage must be filtered
to a maximum of 450 V.
