SSL6203TW
120 V mains dimmable, 12 W linear LED driver
Rev. 1 — 3 November 2014
Objective 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.
2. Features and benefits
2.1 High-voltage integration
Integrated 120 mA (120 V (AC) mains compatible) high-voltage current sources
Integrated bleeder high-voltage current source
Integrated low voltage supply regulator
Two high-voltage current sources per output for optimal heat balancing
Start up Junction Field Effect Transistor (JFET)
Integrated floating switches for improving LED utilization
Robust high-voltage IC with 330 V rating, compatible with 120 V (AC) mains voltage
2.2 Mains dimmable
Leading-edge dimmer compatible (phase-cut)
Adjustable bleeder current by a single resistor
Adjustable LED current by a single resistor or controlled by a current source
Low dimmer inrush current stress due to the absence of an electrolytic capacitor on
the rectified mains

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 Volp has been created. When the string
voltage exceeds Volp, the IC enters the protection mode and the LED current is stopped,
preventing further charging of the capacitor and destructive failure.
