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 VCC passes the VCC(startup) level. The supply can be taken over
by the auxiliary winding of the transformer as soon as VCC is high enough and the supply
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 VCC
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 VCC drops below the VCC(UVLO) level, the IC
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 VRC(max) level and, starting
from a new primary stroke, it discharges to the VRC(min) level. Because the discharge is
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 VBRIGHTNESS is high can be estimated using Equation 1:
1
1
RC = ------- -------- – t ch arg e
3.5 f osc
(1)
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. Figure 3 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.

A typical RC waveform is given in Figure 4. 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 1 nF. 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.

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 %.

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 Vth(SBLEED) level (52 V typically). The weak bleeder switch is
switched on as soon as the voltage on pin ISENSE exceeds the Vth(high)(ISENSE) level
(100 mV typically). The weak bleeder switch is switched off when the ISENSE voltage
drops below the Vth(low)(ISENSE) level (250 mV typically). The weak bleeder switch is also
switched off when the strong bleeder switch is switched on. See Figure 5.

8.5 Valley switching
A new cycle is started when the primary switch is switched on (see Figure 6). 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 Lp Cp
(2)
where:
Lp = primary self inductance
Cp = parasitic capacitance on drain node

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.
Figure 6 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.

Figure 7 shows a typical curve for a reflected output voltage N at an output voltage of
80 V. 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 480 kHz, thus
reducing the switch-on losses to a minimum. At 200 kHz, the next primary stroke is started
at 33 before the valley. The switch-on losses are still reduced significantly.

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 tsup(xfmr_ring) seconds, demagnetization recognition is suppressed.
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 RSENSE
to measure the current. The circuit is activated after the leading edge blanking time tleb.
The protection circuit limits the source voltage over the RSENSE1 resistor to Vth(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
Vth(swp)SOURCE, the IC 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.
8.9 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.

10. Thermal characteristics
The heat sink in the application with the SSL2101 is made with the copper on the
Printed-Circuit Board (PCB). The SSL2101 uses thermal leads (pins 4, 5, 13, 14 and 15)
for heat transfer from die to PCB.
Enhanced thermal lead connection may drastically reduce thermal resistance.
The following equation shows the relationship between the maximum allowable power
dissipation P and the thermal resistance from junction to ambient.
R th j – a = T j max – T amb P
Where:
Rth(j-a) = thermal resistance from junction to ambient
Tj(max) = maximum junction temperature
Tamb = ambient temperature
P = power dissipation
The thermal resistance as a function of the PCB area (Board: 0.8 mm thickness, 2 layers,
Bottom Cu coverage 90 %, Cu thickness 70 m
(390 W/mK), Core material conductivity: 0.5 W/mK, 10 vias dia 0.3 mm) is shown in
