2. Safety warning
Connect the board to the mains voltage. Avoid touching the board while it is connected to
the mains voltage. An isolated housing is obligatory when used in uncontrolled,
non-laboratory environments. Galvanic isolation of the mains phase using a variable
transformer is always recommended.

5. Board information
5.1 Description of the SSL4120T integrated controller
The SSL4120T integrates controllers for the PFC and an HBC. The board provides the
drive function for the:
• discrete MOSFET of the up-converter
• two discrete power MOSFETs in a resonant half-bridge configuration
The internal high-voltage resonant controller provides Zero-Voltage Switching (ZVS) of
the LLC resonant converter. The SSL4120T includes a high-voltage level-shift circuit and
several protection features such as:
• OverCurrent Protection (OCP)
• Open-Loop Protection (OLP)
• Capacitive Mode Protection (CMP)
• general-purpose latched protection input
In addition to the resonant controller, the SSL4120T contains a PFC controller. Efficient
PFC operation is achieved using:
• quasi-resonant operation at high-power levels
• quasi-resonant operation with valley skipping at lower power levels
Safe operation under all conditions is guaranteed using:
• OverCurrent Protection (OCP)
• OverVoltage Protection (OVP)
• demagnetization sensing
Compared to the TEA1713T, the SSL4120T has a higher PFC frequency limit to support
IEC 61000-3-2 Class-C requirements for lighting applications.

The proprietary high-voltage BCD power logic process makes efficient direct start-up from
the rectified universal mains voltage possible. A second low-voltage Silicon-On-Insulator
(SOI) IC is used for accurate, high speed protection functions and control.
The combination of PFC and a resonant controller in one IC makes the SSL4120T an
interesting component for very efficient and small LED driver applications.

5.2 SSL4120T LED demo board block diagram
The board can operate at a mains input voltage of between 90 V and 300 V (universal
mains).
The demo board contains two converter circuits:
• a BCM PFC
• a resonant LLC HBC
The SSL4120T controls both converters.
The demo board is to illustrate SSL4120T operation in a single channel current controlled
LED driver with burst mode operation during dimming. A limitation is that the output
voltage must be between 35 V and 60 V.
The performance is according to today’s general standards and can be used as a starting
point for further development.

Fig 4. SSL4120T LED demo board block diagram
A typical feature of the demo board is burst mode operation which is used to reach the low
LED currents during dimming. An external comparator U2A (shown in the Figure 17)
triggers the bursts.
To reach the low THD values, the PFC on-time is modulated using the SSL4120T
COMPPFC pin. The modulation signal is derived from the mains voltage and it is injected
by capacitor C8a in Figure 17.

After the first switching cycles, the levels become normal for operation and charging of
RCPROT stops.

The VRCPROT level decreases to zero again using the external discharge resistor that is
part of the RCPROT system.
During normal start-up, the initial charging of VRCPROT must not trigger a protection
function (4 V level).
6.4 Efficiency
Efficiency measurements are made measuring the output voltage on the board and the
current through the LED string. The losses in the output connection cable are not taken
into account.

The interruptive character of burst mode can generate unwanted audible noise. Audible
noise levels are low because the burst mode supply only operates at low-power levels.
The burst frequency can be controlled using the:
• hysteresis of comparator circuit U2A (resistor R27);
• output capacitor value (C32, C37);
• speed of the control loop (C36, R43).
Improvements for the LLC transformer can be considered, such as:
• Potting of the transformer windings
• Adding of air gap filler to damp acoustic resonance

Fig 9. HBC switch on/switch off using VSNSOUT in burst mode operation
The GATEPFC is not switched off using the SNSOUT pin. However, when checking the
GATEPFC signal it is sometimes switched off at light loads. The GATEPFC signal is
switched off because the SNSBOOST reaches its OverVoltage Protection (OVP) trigger
level.

Ripple and noise are measured at full output load.
The resonant converter input voltage causes a frequency component in the output current
ripple. The ripple is related to the mains voltage frequency (50 Hz or 60 Hz). The resonant
converter switching frequency causes the other component in the output current ripple.

6.10 No-load behavior
When an LED string or other load is not attached to the current driver, the output voltage
VO rises to a maximum value of approximately 65 V.
The controller then enters the latched protection shut-down state due to OVP using the
SNSOUT pin.

Fig 13. No-load behavior; SNSOUT overvoltage protection
6.12 Short-circuit behavior
A short-circuit on the output of the resonant converter causes the primary current to
increase. The SNSCURHBC function detects the increase causing the IC to run at the
maximum frequency until the protection timer RCPROT reaches the 4 V protection level.
The RCPROT function performs a restart timer function and restarts when the voltage
drops to 0.5 V. After the short-circuit is removed, the converter starts up and operates as
normal.
The RCPROT function is the main protection mechanism. Under certain conditions other
protections are activated during the output short-circuit test. In the demoboard, the SUPIC
voltage is cycles between the UVP level and start level.
Remark: An additional capacitor of 220 F was added to SUPIC for the test in
Figure 14(a) to prevent SUPIC reaching the UVP level.

7. Known limitations
The SSL4120T demo board is not a reference design. It is a demo board to highlight the
features of the SSL4120T IC. There are some known issues with this board.
7.1 No CVCC regulation
This demo board only has a current controlled output. When a load is not connected, the
output rises to 65 V and the board shuts down. Cycling the power restarts the board.
When the load impedance is too high, constant voltage and constant current control
(CVCC) can be use to limit the output voltage to 58 V.
7.2 IO(min) high tolerance
The minimum output current has a high tolerance in this design. It varies between 35 mA
and 50 mA. When designing an LED driver, reduce the minimum current tolerance. A
slightly negative voltage can be applied to the DIM input to reduce the LED current below
IO(min) for testing.
7.3 Limited VO range
The output voltage range is from 35 V to 60 V. Larger voltage ranges are possible when
special circuits are added to supply the IC and feedback amplifier.
7.4 EMI conducted emission
At some frequencies, the EMI test limits are exceeded. The design can be improved with
the following items:
• PFC inductor start of winding: start the winding closest to the core
• PFC inductor: shield
• PFC large signal current loop: reduce area
• EMI input section and the PFC stage: mount a metal shield between them
