Applications
The TPS92692PWP is designed for automotive interior and exterior LED lighting applications including headlamps, DRL, and indicator arrays requiring tight current accuracy and low EMI. Its integrated spread-spectrum modulation is especially valuable in infotainment-adjacent lighting where AM-band radio interference must be minimized. It also suits industrial LED signage and architectural lighting fixtures demanding wide-range dimming from full brightness down to 0.1% duty cycle.

Frequently Asked Questions
How does spread-spectrum modulation in TPS92692PWP help meet automotive EMI standards?
TPS92692PWP dithers its switching frequency by ±15% around the programmed center frequency, spreading the switching energy across a wider band and reducing peak EMI levels by approximately 10 dB to 15 dB. This makes it easier to pass CISPR 25 Class 5 automotive limits for conducted and radiated emissions without large additional EMI filter components.
What dimming range does TPS92692PWP support, and which dimming methods are available?
TPS92692PWP supports a 1000:1 dimming ratio through its internal PWM generator, corresponding to LED currents from 100% down to 0.1% of the set point. It accepts an external PWM signal for digital dimming or an analog voltage for continuous current adjustment, giving lighting designers flexibility for both microcontroller-controlled and potentiometer-based brightness control.
What current sensing accuracy does TPS92692PWP achieve, and why is it critical for automotive LED arrays?
TPS92692PWP achieves average LED current sensing accuracy of ±2% over the operating temperature range of -40°C to 125°C. For multi-string LED headlamp modules where all strings must match luminous intensity within 5%, this ±2% accuracy prevents color or brightness mismatches between channels without per-unit calibration at the manufacturing stage.
Can TPS92692PWP operate at a 12 V automotive battery rail during cold-crank voltage dips?
TPS92692PWP is designed for automotive supply conditions including cold-crank events where the 12 V rail can dip to approximately 6 V for up to 40 ms. The controller maintains regulation across its specified input voltage range, preventing LED flicker during cranking. The HTSSOP-20 thermal pad ensures safe operation during sustained high-duty-cycle conditions at ambient temperatures up to 85°C.
