Selection Guide

Choose the TLD1125ELXUMA1 when driving a single high-current LED string (up to 360 mA) in an AEC-Q100 automotive application such as rear combination lamps, DRL, or turn signals, where the linear-topology EMI benefit and 14-pin PG-SSOP-14-EP footprint with exposed thermal pad are acceptable. Choose the TLD21313EPXUMA1 instead if you need three independently dimmable channels at lower per-channel current (60 mA each) for RGB ambient lighting. Choose the TLF11251LDXUMA1 if you need the TLF11251L variant of the LITIX family on the same footprint. For non-automotive or lower-current applications, a discrete resistor-based LED driver may suffice, but at the cost of current accuracy and protection features.

Linear topology eliminates inductor EMI (vs Switching LED driver (e.g. buck topology))

Design Notes

Estimated: in linear LED-driver topology, the IC dissipates P = (VIN - VLED) x ILED. At VIN = 14 V (automotive nominal), VLED = 9 V (three white LEDs), and ILED = 360 mA, dissipation is about 1.8 W. The PG-SSOP-14-EP exposed thermal pad must be soldered to a PCB copper pour of at least 1 square inch to maintain the junction temperature below 150 C. If VIN rises above VLED by more than 5 V, de-rate ILED or add external heatsinking. Always cross-check with the thermal-resistance data in the manufacturer datasheet.

Place the supply decoupling capacitor (typically 100 nF ceramic) as close as possible to the IN pins. Keep the high-current loop from IN to LED to ground as short as possible to minimize parasitic inductance. The exposed thermal pad requires thermal vias (typically 5-9 vias of 0.3 mm diameter) directly beneath the pad to conduct heat into inner PCB copper layers. Pin 1 indicator dot identifies the orientation during optical inspection.

Do not connect the diagnostic pin to voltages above the absolute maximum rating. During load-dump events (ISO 7637), VIN can surge up to 40 V - ensure the input capacitor and TVS protection support the application. The PWM input should be driven from a clean logic signal - any glitch on PWM appears as visible LED flicker. For diagnostic-flagged open-LED conditions, route the DIAG signal back to the body-control MCU for fault logging per automotive OEM requirements.
