Product details

Switching frequency and topology flexibility

The 80 kHz to 700 kHz range lets you tune the power stage. 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.

Frequently asked questions

Is TPS92691QPWPTQ1 AEC-Q100 qualified for automotive use?

Yes, the TPS92691QPWPTQ1 is part of the Automotive, AEC-Q100 series. That qualification covers the full production flow and makes the part suitable for PPAP submissions in Tier-1 and OEM automotive lighting applications.

What is an equivalent part or replacement for TPS92691QPWPTQ1?

It is not a pin-compatible replacement for the TPS92691QPWPTQ1, but it covers simpler boost LED-driver designs where an integrated switch and lower output current are acceptable.

What topologies does TPS92691QPWPTQ1 support?

It supports flyback, SEPIC, step-down (buck), and step-up (boost) topologies. That flexibility lets one controller design cover isolated, battery-voltage-crossing, and conventional step-down or step-up LED strings.
