The LT3796IFE-1#PBF is a high-performance LED controller integrated circuit from Linear Technology, designed to manage and drive high-power LEDs with precision and efficiency. This advanced IC is well-suited for applications requiring high-brightness LED lighting, such as automotive headlamps, industrial lighting, and architectural illumination.

Key Features

• Wide Input Voltage Range: The device operates from an input voltage range of 4.5V to 60V, making it versatile for various power supply conditions.
• Constant-Current and Constant-Voltage Regulation: It provides accurate constant-current (±3%) output to ensure uniform brightness of LEDs and also supports constant-voltage regulation for battery charging and power supplies.
• High-Side Current Sense: With high-side current sensing, the LT3796IFE-1#PBF can provide better accuracy and is less sensitive to the ground noise that can affect low-side sensing.
• True Color PWM Dimming: The device offers true color pulse-width modulation (PWM) dimming, which delivers constant LED color with varying brightness levels.
• Robust Thermal Performance: Housed in a thermally efficient TSSOP-28 package, it can withstand and dissipate heat effectively, ensuring reliable performance even in high-power applications.
