SSL2101 NXP Semiconductors Dimmable Greenchip driver for LED lighting 8. Functional description The SSL2101 is an LED driver IC that operates directly from the rectified mains. The SSL2101 uses on-time mode control and frequency control to control the LED brightness. The BRIGHTNESS and PWMLIMIT input of the IC can be used to control the LED light output in combination with an external dimmer. The PWMLIMIT input can also be used for Thermal Lumen Management (TLM) and for precision LED current control. 8.1 Start-up and UnderVoltage LockOut (UVLO) Initially, the IC is self-supplying from the rectified mains voltage. The IC starts switching as soon as the voltage on pin V passes the V level. The supply can be taken over CC CC(startup) by the auxiliary winding of the transformer as soon as V is high enough and the supply CC from the line is stopped for high efficiency operation. Alternatively the IC can be supplied via a bleeder resistor connected to a high voltage. Note however the maximum V CC voltage rating of the IC. If for some reason the auxiliary supply is not sufficient, the high-voltage supply can also supply the IC. As soon as the voltage on pin V drops below the V level, the IC CC CC(UVLO) stops switching and will restart from the rectified mains voltage, if the internal current delivered is sufficient. 8.2 Oscillator An internal oscillator inside the IC provides the timing for the switching converter logic. The frequency of the oscillator is set by the external resistors and the capacitor on pin RC and pin RC2. The external capacitor is charged rapidly to the V level and, starting RC(max) from a new primary stroke, it discharges to the V level. Because the discharge is RC(min) exponential, the relative sensitivity of the duty factor to the regulation voltage at low duty factor is almost equal to the sensitivity at high duty factors. This results in a more constant gain over the duty factor range compared to Phase Width Modulated (PWM) systems with a linear sawtooth oscillator. Stable operation at low duty factors is easily realized. The frequency of the converter when V is high can be estimated using Equation1: BRIGHTNESS RC = ---1-------1-----–t  (1) 3.5 f charge osc R equals the parallel resistance of both oscillator resistors. C is the capacitor connected at the RC pin (pin 8). The BRIGHTNESS input controls the frequency reduction mode. Figure3 shows that the oscillator switches over from an RC curve with R1 in parallel with R2 to R1 only. A low BRIGHTNESS voltage will reduce the switching frequency.

Brightness control block A typical RC waveform is given in Figure4. The RC switch-over threshold is controlled by the BRIGHTNESS pin. To ensure that the capacitor can be charged within the charge time, the value of the oscillator capacitor should be limited to 1nF. Due to leakage current, the value of the resistor connected between the RC pin and the ground should be limited to a maximum of 220 k. Voltage (mV) RC voltage rc_threshhold 75 mV time 014aaa582 Fig 4. Brightness timing waveform 8.3 Duty factor control The duty factor is controlled by an internally regulated voltage and the oscillator signal on pin RC. The internal regulation voltage is set by the voltage on the PWMLIMIT pin. A low PWMLIMIT voltage will results in a low on-time for the internal power switch. The minimum duty factor of the switched mode power supply can be set to 0 %. The maximum duty factor is set to 75%.

SSL2101 NXP Semiconductors Dimmable Greenchip driver for LED lighting 8.4 Bleeder for dimming applications The SSL2101 IC contains some circuitry intended for mains dimmer compatibility. This circuit contains two current sinks that are called bleeders. A strong bleeder is used for zero-cross reset of the dimmer and triac latching. A weak bleeder is added to maintain the hold current through the dimmer. The strong bleeder switch is switched on when the maximum voltage on pin WBLEED and SBLEED is below the V level (52 V typically). The weak bleeder switch is th(SBLEED) switched on as soon as the voltage on pin ISENSE exceeds the V level th(high)(ISENSE) (100mV typically). The weak bleeder switch is switched off when the ISENSE voltage drops below the V level (250 mV typically). The weak bleeder switch is also th(low)(ISENSE) switched off when the strong bleeder switch is switched on. See Figure5.

Bleeder circuit 8.5 Valley switching A new cycle is started when the primary switch is switched on (see Figure6). After a time determined by the oscillator voltage, RC and the internal regulation level, the switch is turned off and the secondary stroke starts. The internal regulation level is determined by the voltage on pin PWMLIMIT. After the secondary stroke, the drain voltage shows an oscillation with a frequency of approximately: 1 ---------------------------------------------- (2) 2 L C  p p where: L = primary self inductance p C = parasitic capacitance on drain node p SSL2101 All information provided in this document is subject to legal disclaimers. © NXP B.V. 2011.

SSL2101 NXP Semiconductors Dimmable Greenchip driver for LED lighting As soon as the oscillator voltage is high again and the secondary stroke has ended, the circuit waits for a low drain voltage before starting a new primary stroke. Figure6 shows the drain voltage together with the valley signal, the signal indicating the secondary stroke and the RC voltage. The primary stroke starts some time before the actual valley at low ringing frequencies, and some time after the actual valley at high ringing frequencies. primary secondary secondary stroke stroke ringing drain valley secondary stroke A RC regulation level B oscillator 014aaa572 A: Start of new cycle with valley switching. B: Start of new cycle in a classical PWM system. Fig 6. Signals for valley switching, flyback configuration Figure7 shows a typical curve for a reflected output voltage N at an output voltage of 80V. This voltage is the output voltage transferred to the primary side of the transformer with the factor N (determined by the turns ratio of the transformer). It shows that the system switches exactly at minimum drain voltage for ringing frequencies of 480kHz, thus reducing the switch-on losses to a minimum. At 200kHz, the next primary stroke is started at 33 before the valley. The switch-on losses are still reduced significantly.

Typical phase of drain ringing at switch-on (at NV =80V) o 8.6 Demagnetization The system operates in discontinuous conduction mode if the AUX pin is connected. As long as the secondary stroke has not ended, the oscillator will not start a new primary stroke. During the first t seconds, demagnetization recognition is suppressed. sup(xfmr_ring) This suppression may be necessary in applications where the transformer has a large leakage inductance and at low output voltages. 8.7 Overcurrent protection The cycle-by-cycle peak drain current limit circuit uses the external source resistor R SENSE to measure the current. The circuit is activated after the leading edge blanking time t . leb The protection circuit limits the source voltage over the R 1 resistor to V , SENSE th(ocp)SOURCE and thus limits the primary peak current. 8.8 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 threshold voltage V , the IC stops switching. Only a power-on reset will restart normal operation. th(swp)SOURCE The short-winding protection also protects in case of a secondary diode short circuit. 8.9 Overtemperature protection Accurate temperature protection is provided in the device. 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. 1.
