Buck topology LED drivers are an effective solution if the LED string voltage is always lower than the battery voltage. However, since the battery voltage varies significantly in cold crank or load dump conditions, many applications require LED drivers that can be configured as a boost, buck-boost, SEPIC, Flyback or Cuk topologies. Ultimately, the LED driver must provide a constant output current to the LEDs in all possible operating conditions. TI’s flexible, single-stage LED driver products are highly configurable pointof-load solutions with advanced dimming capabilities. With diagnostic and protection features in addition to EMI mitigation techniques like spread spectrum, TI’s portfolio provides the necessary functionality to create robust, high-performance platform electronic solutions for single feature front lighting functions. 1 or 2 Series LEDs 3 or More Series LEDs LED Driver Module 5.5VDC to LED Driver Module 4.5VDC to TPS92515HV-Q1 65VDC Buck Current Regulator To BCM Microcontroller TPS92692-Q1 65VDC Binning and Thermal Foldback Buck/Boost Current Regulator Binning and Thermal Foldback To BCM LED Driver Module 6VDC to LM3409HV-Q1 75VDC Buck Current Regulator To BCM Microcontroller Device LED Driver Module 4.5VDC to # of Channels Binning and Thermal Foldback Input Voltage TPS92691-Q1 65VDC Buck/Boost Current Regulator To BCM Microcontroller Output Voltage Binning and Thermal Foldback Internal Switch(s) Min Max Min Max Max LED Current Special Features No 4.5V 65V 2.5V 65V No Limit Analog & PWM Dimming, Spread Spectrum, Fault Handling 1 No 4.5V 65V 0 65V No Limit Analog & PWM Dimming, Fault Handling, Rail-Rail Current Sense 1 Yes 5.5V 65V 0 65V 2A Analog & PWM Dimming 1 No 6.0V 75V 0 75V No Limit Analog & PWM Dimming Multi-Topology Current Regulator TPS92692-Q1 1 Multi-Topology Current Regulator TPS92691-Q1 Buck Current Regulator TPS92515HV-Q1 Buck Current Regulator LM3409HV-Q1 3 Front Lighting – Complete LED Headlamp Modular solution enabling scalable headlight architecture with adaptive functionality Vehicles adopting LEDs for many exterior lighting functions can benefit from a full LED ECU platform approach based on a dual-stage power conversion architecture. This approach consists of a boost voltage pre-regulator stage that creates a stable DC voltage supply for a high-bandwidth buck LED current regulator output stage. TI’s portfolio includes boost voltage pre-regulators with fault handling and spread spectrum EMI features as well as dual-buck current controllers that employ a quasi-hysteretic control topology to handle dynamic LED loads and to enable advanced dimming capabilities. The TPS92662-Q1 LED matrix manager is a perfect solution to provide pixel-level control of the LEDS for dynamic headlight functions like sequential turn-signals and adaptive front lighting. Using front-facing cameras for vehicle and object detection, an LED matrix solution enables vehicles to automatically adjust the intensity of light emitted from the high/low beams without physical movement of the headlamps to create optimal roadway illumination.

TI’s new TPS9261x-Q1 single-channel linear LED driver family enables more styling possibilities for signal and convenience lighting applications, such as the ones outlined in the diagram below. Higher current accuracy, fewer system components, and more system protection have become the most critical design considerations for automotive design engineers. TI’s TPS9261x-Q1 LED driver family offers differentiated output capabilities, packages, and diagnostic features, allowing design engineers to simplify their system by replacing many discrete components that would typically be used to achieve the same functionality.
