1. Introduction
WARNING
Lethal voltage and fire ignition hazard
The non-insulated high voltages that are present when operating this product, constitute a
risk of electric shock, personal injury, death and/or ignition of fire.
This product is intended for evaluation purposes only. It shall be operated in a designated test
area by personnel qualified according to local requirements and labor laws to work with
non-insulated mains voltages and high-voltage circuits. This product shall never be operated
unattended.
The SSL2108X is a family of high-voltage Integrated Circuits (IC), designed to drive
non-dimmable retrofit LED lamps in general lighting applications. The product family
consists of four ICs with different configurations which are shown in Table 1.

[1] SO12 package variants have more fused leads for lower thermal resistance and can be used when a higher
output power is needed.
Main benefits of the product family are:
• Small Printed-Circuit Board (PCB) footprint providing a compact solution
• High-efficiency (up to 95 %)
• Ease of integration
• Low electronic Bill Of Material (BOM)
The SSL2108X provides accurate output control with more than 5 % LED current
accuracy. The ICs can operate using Pulse-Width Modulation (PWM) dimming and have
many protection features including easy external temperature feedback.
The SSL2108X driver family is the high performance solution for the next generation of
retrofit LED lamps. These ICs provide a high efficiency, high-power factor solution in a
small form factor.
Remark: Unless otherwise stated all voltages are in V (DC).

2. Safety warning
This reference board is connected to a high AC voltage (up to 250 V). Avoid touching the
demo board during operation. An isolated housing is obligatory when used in
uncontrolled, non-laboratory environments. Galvanic isolation of the mains phase using a
fixed or variable transformer (Variac) is always recommended. These devices are
recognized by the symbols shown in Figure 1

5. Connection data
The evaluation board operates from either:
• SSL21081 and SSL21082: 100 V (AC) to 120 V (AC) mains supply voltage
• SSL21083 and SSL21084: 230 V (AC) mains supply voltage
The evaluation board is designed to work with an LED module with an operating voltage
of:
• SSL21081 and SSL21082: 60 V
• SSL21083 and SSL21084: 120 V
Loads consisting of multiple high-power LEDs in series with similar operating voltages can
also be used. A dedicated SHARP GW5BDQ27KK3 LED load for connecting to connector
K2A is available on request. Other loads can be connected to either connector K2A or K3.
When attaching an LED load to a board under power (hot plugging), an inrush peak
current occurs due to discharge of capacitor C3. After several discharges, the LEDs will
deteriorate or become damaged.
Jumper settings J1A to J6A shown in Table 4 set the package-specific circuitry to enable
each device to function correctly.

5.1 The board connections
When connecting the evaluation board consider the following:
• Place a galvanic isolated transformer between the AC source and the evaluation
board connector K1A, if used.
• Connect a user-defined LED module to connector K2A or K3. Ensure that the anode
of the LED module is connected to one of the positive LED terminals.
• Connector K4 can be used:
– to connect an external NTC resistance. Remove the pre-soldered NTC RT1 (see
Ref. 1)
– to use a PWM dimming signal to the converter (see Ref. 1)

6. Functional description
The SSL2108X IC (Ref. 1) uses Boundary Conduction Mode (BCM) with peak current
control. The SSL2108X controls and drives the converter. In addition, the SSL2108X
offers a low component count LED buck converter solution. Valley switching and PWM
dimming are implemented into the SSL2108X together with several protection features:
• UnderVoltage LockOut (UVLO)
• Leading-Edge Blanking (LEB)
• OverCurrent Protection (OCP)
• Internal OverTemperature Protection (OTP)
• Brownout protection
• Short-Winding Protection (SWP)
• Output Short Protection (OSP)
• NTC over temperature control and protection
Both the SWP and the OSP are latched protections circuits. These protective features
cause the IC to halt until a reset is executed. If VCC drops below its restart level, the IC
resets the latched protection mode. Restarting the evaluation board is done by removing
AC mains supply voltage. All other protective features cause a safe restart of the
converter. Refer to the SSL2108X data sheet for detailed information on all protective
features.
Depending on the selected SSL2108X version, the evaluation board is optimized for an
LED voltage, LED current and resulting output power. See Table 2. As a default, jumper
J7A is set to apply the full output power to the LED load. Setting jumper J8A or J9A
instead reduces the output power to either 66 % or 33 % of the original output power.
Remark: Do not remove or set jumpers when the board is connected to the AC mains
supply voltage because LED damage can occur.

Jumper J10A is connected in series with the brownout capacitor C8. Removing this
jumper sets the brownout protection trigger values to be reset to default value.
Remark: Brownout protection is only available in the SSL21082 and SSL21084.
TVS Diode D2 is present to protect the DC circuit against overvoltage.
7. Board optimization
The EMC filter calculations for components C1, C2, L1 are described in AN11041 (see
Ref. 2). On the evaluation board, L2 and C8 have been added to provide extra filtering to
meet EMC norms.
Power factor of the evaluation board depends mainly on the input resistance of the input
fused resistor FUS1. A higher resistance proportionally increases the power factor but
reduces the overall efficiency of the evaluation board.
Another way to get higher power factor is to add a valley fill circuit. The valley fill circuit
improves power factor with reduced efficiency losses. The disadvantage is the higher
component count needed. Figure 12 gives an overview for the SSL21081 of input
resistance as a function of power factor and efficiency.

7.1 Active bypass
An increased value for the inrush current resistor causes the board to operate with the
most phase cut dimmers, but also lowers the efficiency. If a higher power factor is not
required, but leading-edge dimmer compatibility and high efficiency are important, the
active bypass option is available. In this circuit, the inrush current resistor is bypassed
using an SCR (see Figure 13).

8. Negative Temperature Coefficient (NTC) function
The NTC pin can act as a control for thermal protection, an input for disabling/enabling the
light output using PWM dimming and a soft-start function.
When using the NTC pin as a control for thermal protection, the pre-soldered NTC RT1
can be used. Alternatively, a user-defined NTC resistor can be directly connected to this
pin through connector K4. Remove the pre-soldered NTC RT1 in this case. If necessary, a
resistor R6 can be mounted to fine-tune the NTC protection. As the default, a 0
resistance is mounted.
In addition, a PWM signal can be connected to connector K4, making PWM dimming
possible. Capacitor C7 is used as the soft-start capacitor. When using the soft-start
capacitor, the NTC protection function changes from auto-restart protection to a latched
protection.
Remark: Detailed information on the NTC function can be found in the SSL2108X
data sheet (see Ref. 1).

11. Printed-Circuit Board (PCB) data
11.1 Evaluation board photographs
Remark: The configuration of the SSL21083 is similar to the SSL21081 although BOM is
different. The same is true of the SSL21084 when compared to the SSL21082.
The evaluation board shown in Figure 15 is a large format footprint. Its size enables the
full functionality of the SSL2108X IC family to be highlighted. The measurement pins,
connectors and other components are used to allow any one of the SSL2108X ICs to be
dropped in to place.
Figure 16 shows the SSL21081 reference board which can be used in retrofit lamp
designs. It is clear that the total form factor is reduced using the SSL2108X ICs in a
real-world application. A PCB size reduction and thus an efficiency of more than 92 % can
be reached.
