LM3463 Dynamic Headroom Controller with Thermal Control Interface and Individual Channel Dimming Control

DESCRIPTION
The LM3463 is a six channel linear LED driver with Dynamic Headroom Control (DHC) interface that is
specialized for high power LED lighting applications. The variation of the output current of every output channel in the temperature range of -40°C to 125°C is well controlled to less than ±1%. The output current of every channel is accurately matched to each other with less than ± 1% difference as well.

FEATURES
• Dynamic Headroom Control output to maximize efficiency
• 6 channels current regulated LED driver
• High precision analog dimming control interface
• 4 individual PWM dimming control input
• Dimming control via digital data bus
• Built-in maximum MOSFET power limiting mechanism
• Allows cascade operation to extend the output channels
• Fault indicator output
• Thermal shutdown
• UVLO with hysteresis
• 48L LLP package

APPLICATIONS
• Streetlights
• Solid State Lighting Solutions
