All rights reserved. 4 of 15 SSL2115X NXP Semiconductors Low-cost non-dimmable LED driver IC Where • Vref(high)pk is the peak high reference voltage • RSOURCE is the value of the resistor connected to the SOURCE pin 8.3 Leading-Edge Blanking (LEB) The controller has a fixed LEB of 325 ns to avoid wrong detection of the primary peak current. 8.4 dV/dt detection The end of demagnetization is detected when the voltage on the sense pin is <50 mV. 8.5 Turn-off-time (toff) A blanking time is applied at the beginning of toff during tblank time to observe the demagnetization. 8.6 Supply concepts VCC and UnderVoltage LockOut (UVLO) An integrated Junction gate Field-Effect Transistor (JFET), connected to the drain voltage, provides the start-up current. The IC starts switching when the voltage on pin VCC exceeds the VCC(startup) level. After start-up, an external supply is required, which an auxiliary winding connection can provide. When the voltage on pin VCC drops below the VCC(UVLO) level, the IC stops switching and is reset. Design the voltage of the auxiliary winding to ensure that the VCC supply voltage has a Umax value of 29 V 8.7 Peak current detection The cycle-by-cycle peak drain current limit circuit uses the external source resistor RSOURCE to measure the primary peak current. The circuit is activated after the leading edge blanking time. The protection circuit limits the source voltage over resistor RSOURCE to Vth(det)SOURCE, thus limiting the primary peak current. 8.8 LED OverTemperature Protection (OTP) An external temperature dependent resistor can be applied for LED over temperature protection. 8.9 LED Output Short-circuit Protection (OSP) When the output short-circuit protection is activated, the IC enters shutdown mode. Only a power-on reset (switching off the mains voltage) activates normal operation. 8.10 Output LED open-circuit protection If an open circuit occurs on the LEDs, the output voltage increases at each cycle of the AC/DC converter. Energy is no longer transferred to the LEDs. The energy accumulated at the primary side is transferred to the supply of the IC via the auxiliary winding.

All rights reserved. 5 of 15 SSL2115X NXP Semiconductors Low-cost non-dimmable LED driver IC limits the VLED when VCC reaches the Vprot(VCC) value. A non-latched application can be created depending on implementation of a small preload. Without the small preload, the protection latches. 8.11 Operational limits The application must stay in Current Control Mode (CCM) for normal functionality. During normal operation, the switching frequency can reach 0.85 fsw(high). This requirement must be met for the highest specified LED voltage. On the other hand, the converter must be capable to handle the lowest specified LED voltage. The auxiliary winding of the transformer generates the IC’s VCC supply voltage. As the minimum and maximum requirements for the supply voltage of the IC have a given ratio, the ratio of the lowest and highest LED voltage is also determined. Choose the auxiliary voltage carefully if a large LED voltage ratio is required. An LED voltage ratio up to three can be realized with this IC. The open output protection limits the output voltage to Umax / 0.85 when the circuit is designed according to the guidelines contained in this data sheet.
