• Configurable current sources with ground-aligned, to maximize peak LED efficiency.
• Quiet and reliable operation over full temperature range.
• Reduced system cost by consolidated power, space, and noise.
• High performance isolation circuit.
• High current level scaling.

Applications

Primarion SSL21084T/1,118 LED Driver provides an ideal solution for many different applications, including:

• Adjustable indoor or outdoor lighting.
• HVAC (Heating, Ventilation, and Air Conditioning) control.
• Automotive headlight control.
• Industrial illumination.

Working Principle

Primarion SSL21084T/1,118 LED Driver has two independent “constant-current sink” channels. The two independent channels that can each put out between 1 mA to 118 mA with minimum output voltage of 11.6V . The two channels can be independently configured with either common anode or common cathode, allowing for flexibility for different system designs. The integrated precision DACs also provide an accuracy of +/- 1% of full scale current.

The LED Driver board includes an integrated high frequency power stage to minimize power consumption, minimize cross-talk and interference between the channels, and to minimize the electrical noise generated.

The device also includes an integrated high-efficiency power supply circuit to ensure best possible performance at any load and temperature condition. The LED Driver utilizes the principles of pulse-width modulation and current-source control to deliver superior LED performance during varying load or temperature conditions. In addition, the LED Driver includes an isolation circuit to reduce the risk of electrical shock.

Primarion SSL21084T/1,118 LED Driver has excellent temperature range operating performance and is highly resistant to noise and other electrical disturbances. The isolation circuit provides superior isolation characteristics over the entire temperature range, thereby providing the highest level of protection against electrical shock.

Overall, the Primarion SSL21084T/1,118 LED Driver is an excellent choice for a wide variety of LED lighting applications, providing superior performance and reliability over a wide temperature range.
