Product data sheet
1. General description
The SSL6203TW is a monolithic high-voltage Integrated Circuit (IC) that can drive and
dim three high-voltage LED strings directly from the rectified mains. The high level of
integration gives a low-cost and low component count application, which is especially
suitable for retrofit Solid-State Lighting (SSL).
The IC operates as a linear high-voltage current source. The string current in the LEDs
can easily be adjusted. A patented LED drive scheme ensures optimal LED utilization.
The application can be dimmed. It also runs on a leading-edge phase cut dimmer with the
integrated smart bleeder current.
To guarantee correct and proper operation, the SSL6203TW incorporates many protection
features.
A thermally enhanced small outline package gets rid of the heat and makes integration of
the whole application on the LED plate possible.

7. Functional description
7.1 Linear LED driver operation
The linear LED driver in the SSL6203TW operates as a high-voltage linear current source.
This current source is used to drive the LEDs. Figure 3 shows a basic application
diagram. Depending on the momentary value of the rectified mains voltage, the LED
current flows through one or more LED strings.
To equalize the LED string on-times, integrated high-side switches short-circuit the LED
strings at the appropriate moment. To set the required LED current ripple, additional
capacitors can be added across every LED string. The application can be dimmed. Close
to the mains zero crossing the LED current is off. To keep the dimmer in the on-state, a
bleeder current starts to draw current.

SSL6203TW basic application diagram
7.2 Protection mode and VDD supply generation
During start-up, the voltage on the VDD pin is < VDD(stop). The IC is in protection mode.
When the mains voltage is applied to the SSL6203TW system (see Figure 1), an
integrated JFET enables the supply voltage generation. The VDD control loop charges the
external capacitor CVDD and regulates the VDD voltage.
After CVDD has been charged to > VDD(start) level, the IC proceeds to start-up mode.
Should the voltage on the VDD pin drop to below VDD(stop), the IC enters the protection
mode again.

7.3 Start-up mode
After the supply voltage has been ramped up and no other protections are active, the IC
proceeds to start-up mode. To ensure a fast start-up without excessive dissipation in the
IC, the charging current of the LED capacitor is dynamically adjusted to the mains voltage
in start-up mode.
7.4 Normal mode
The IC proceeds to normal operation if none of the protections (UVLO, OTP, or OLP) are
active and the LED capacitors have been sufficiently charged. Measuring the current into
the OV pin detects that the LED capacitors are sufficiently charged. When the current into
the OV drops to below Ith(OV), the transition to normal mode can be made. In normal
mode, the internal High-Voltage LED Current Source (HVLCS) is operational. The
selected string output (STR1x, STR2x, STR3x) conducts.
The HVLCS current can be calculated with Equation 1:
I HVLCS = I LED min + max M LED I I LED – I I OV ,0
(1)
During normal operation, the bleeder system is enabled. The High-Voltage Bleeder
Current Source (HVBCS) ensures that the dimmer is always biased with a minimum
current (hold current). The HVBCS current can be calculated with Equation 2:
I HVLCS
I HVBCS = I bleed min + max M BLEED I I BLEED – ----------------- ,0
M LED
(2)
The currents described by Equation 1 and Equation 2 reflect the DC values of the current.
In an application with a leading-edge dimmer, the mains is phase-cut, resulting in a
reduced average current because of a reduced duty cycle. The average LED current can
drop to below a few percents of the maximum value.
7.5 IC dissipation reduction
In normal operation, the number of series connected LED strings is selected according to
the available RECT voltage. This selection maximizes the efficiency and minimizes the
dissipation in the HVLCS.
Adding a series resistor to the STR1B, STR2B, and STR3B paths can further reduce the
IC dissipation. The SSL6203TW prioritizes the HVLCS current through these paths so that
dissipation takes place in the external resistors rather than in the IC. The remaining
current flows into the STR1A, STR2A, and STR3A branches so that the total string current
matches the LED current setting.
7.6 LED utility enhancement
The SSL6203TW optimizes the LED string switching pattern ensuring that at full power
the average current of all the LED strings is almost identical. The optimization causes all
LEDs to be used at maximum performance. Figure 4 shows the calculated normalized
LED utilization per string for the SSL6203TW versus the average utilization per string in
conventional solutions.

7.7 Line/load regulation
A linear LED driver is sensitive to line and load variations as they affect the on-time of the
LEDs (which influences the emitted light) and the dissipation in the IC. To get a more
stable line/load regulation and a more constant IC dissipation, negative feedback is
available through the OV pin. The feedback reduces the LED current as the mains current
voltage increases, stabilizing the IC dissipation. Zener diode ZOV and resistor ROV
(see Figure 3) can set the starting point and the sensitivity of the feedback.
Figure 6 shows the calculated effect of this feedback and with resulting line/load
regulation.

7.8 OverTemperature Protection (OTP)
The OTP is triggered when the die temperature reaches the Tth(act)otp level. In that case,
the IC changes to protection mode and the currents through the high-voltage current
sources (both the LED and bleeder) are switched off. If the die temperature drops to below
Tth(rel)otp, normal operation is resumed.
7.9 Open LED Protection (OLP)
If an LED string is open, the differential string voltage continues to rise. To protect the
external buffer capacitor, an overvoltage threshold Vth(olp) has been created. When the
string voltage exceeds Vth(olp), the IC enters the protection mode and the LED current is
stopped, preventing further charging of the capacitor and destructive failure.

8. LED selection
8.1 Introduction
The SSL6203TW is designed to drive three LED strings in a 120 V (AC) mains
application. For a proper operation of the application, it is important to select suitable
LEDs. Below some guidelines are given. Detailed information can be found in the
application note AN11617, SSL6203TW 120 V 12 W linear LED driver.
8.2 LED voltage rating
Suitable LEDs for use in an SSL6203TW application are 48 V high-voltage LEDs. A series
connection of lower voltage LEDs, which sum up to about the same voltage level is also
possible. Some considerations for selecting the LED voltage:
• When 10 % mains voltage variation is assumed, the minimum peak voltage of the
mains in a 120 V (AC) system equals: 0.9 120 2 = 152.7 V
• The bridge rectifier and the surge resistor have some voltage drop (see Figure 3)
• Voltage drop on series diodes D1, D2, and D3
• Voltage head room required for the SSL6203TW LED current source. For proper
operation of the high-side switches, the IC must have 14 V on the internal LED current
source
• LED voltage at its operating temperature
The remaining voltage must be high enough to accommodate three LED string voltages.
The SSL6203TW incorporates an integrated Open LED Protection (OLP). The voltage of
the selected LED must be lower than the Vth(olp) level (see Section 12).
8.3 LED current rating
The maximum LED string current of the SSL6203TW can be set using the LED pin current
biasing. The maximum set LED string current must be 120 mA or less. The selected LEDs
must be able to handle the set LED string current. It is possible to place LEDs in parallel to
divide the total string current over more LEDs.
