SMPS ICs for mains LED drivers
8.9 OverTemperature Protection (OTP)
An accurate temperature protection is provided in the device. When the junction
temperature exceeds the thermal shutdown 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.
8.10 OverVoltage Protection (OVP)
Overvoltage protection can be achieved in the application by pulling pin REG above its
normal operation level. The current primary stroke is terminated immediately. 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.
8.11 Characteristics of complete LED power supply
8.11.1 Input
The input voltage range comprises the universal AC mains from 80 V to 276 V.
8.11.2 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.
8.11.3 Efficiency
An efficiency over 80 % at maximum output power can be achieved for a complete
converter designed for universal mains.
8.11.4 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 Equivalent Series Resistance ( ESR) of
the output capacitor.
8.11.5 Output
The SSL152x family can operate over a wide range of output power levels up to 15 W
determined by the value of RDson.
