At the low end you get better efficiency and less gate-drive loss; at the high end you shrink the inductor and output capacitor, which matters when board space is tight in a compact LED module. The controller handles flyback for isolated designs, SEPIC for battery-voltage ranges that cross the LED string voltage, and buck or boost for conventional step-down or step-up strings. One BOM line covers multiple platforms if the LED voltage and current requirements fall within the 65 V output rating. ## Dimming methods and output control Both analog and PWM dimming are supported. Analog dimming adjusts the LED current continuously for applications where PWM noise is undesirable (interior ambient lighting, display backlighting). PWM dimming gives a wider effective dimming ratio and is the standard choice for headlamp low-beam / high-beam switching or DRL intensity steps. The single output drives one LED string; multiple controllers are ganged for multi-channel designs such as matrix headlamps. ## Packaging and mounting The 16-HTSSOP package (4.40 mm width, exposed thermal pad) is a surface-mount PowerTSSOP. The exposed pad must be soldered to a copper land on the PCB and connected to the ground plane with thermal vias to keep the junction temperature within the -40°C to 125°C operating range under full load. The part is supplied in Tape & Reel or Cut Tape, which is the standard format for automated pick-and-place assembly.","metaTitle":"TPS92691QPWPTQ1 LED Driver Controller, AEC-Q100, 65V","metaDescription":"TI TPS92691QPWPTQ1 automotive LED DC/DC controller.
