TEA1623P; TEA1623PH
STARplug switched mode power supply controller IC
8.6 Protection
8.6.1 Overcurrent protection
The cycle-by-cycle peak drain current limit circuit uses the external source resistor RI (see
Figure 7) to measure the current. The circuit is activated after the leading edge blanking
time tleb. The protection circuit limits the source voltage to Vsource(max), and thus limits the
primary peak current.
8.6.2 Short-winding protection
The short-winding protection circuit is also activated after the leading edge blanking time.
If the source voltage exceeds the short-winding protection voltage Vswp, the TEA1623
stops switching. Only a power-on reset will restart normal operation. The short-winding
protection also protects in case of a secondary diode short circuit.
8.6.3 OverTemperature Protection (OTP)
An accurate temperature protection is provided in the TEA1623. When the junction
temperature exceeds the thermal shut-down temperature, the IC stops switching. During
thermal protection, the IC current is lowered to the start-up current. The IC continues
normal operation as soon as the overtemperature situation has disappeared.
8.6.4 OverVoltage Protection (OVP)
Overvoltage protection can be achieved in the application by pulling pin REG above its
normal operation level, or by keeping the level of pin AUX above Vdemag. 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 pin REG must be limited.
8.7 Characteristics of the complete power-plug
8.7.1 Input
The input voltage range comprises the universal AC mains from 80 V to 276 V.
8.7.2 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.
8.7.3 Efficiency
An efficiency of 75 % at maximum output power can be achieved for a complete converter
designed for universal mains.
8.7.4 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.
