TLD60992ESXUMA1 Overview
What is a multi-topology LED driver? A multi-topology LED controller is a switching regulator IC that the designer can configure as a boost, buck, buck-boost (SEPIC), or flyback converter by changing the external component arrangement, while keeping the controller IC itself fixed. Within the broader taxonomy, it sits under switching controllers -> DC-DC controllers -> LED drivers -> power management ICs -> semiconductors, and belongs to Infineon's LITIX automotive lighting family.
Key features include analog and PWM dimming inputs per channel, integrated MOSFET gate drivers, and built-in protection features (over-voltage, over-current, open-LED, and thermal shutdown). The dual-output architecture supports two independent LED strings with individual dimming control, while the high switching frequency of 2.2MHz allows miniature inductors and reduced PCB area. The wide 4.5V-58V input accommodates both 12V and 24V automotive bus rails, including load-dump transients.
Technically, the device uses a peak-current-mode control architecture with slope compensation, providing cycle-by-cycle current limiting and good transient response. The exposed pad (PG-TSDSO-24-5) package offers a low thermal resistance path for the internal gate drivers, which is essential when driving external MOSFETs at high frequency and high input voltage.
Typical applications include automotive front-light LED drivers (headlamp low/high beam, daytime running light), rear-light LED drivers (tail, brake, indicator), architectural and industrial lighting, and any multi-string LED system requiring independent dimming or fault handling.
When designing with the TLD60992ESXUMA1, choose the topology (boost, buck, SEPIC, flyback) based on LED string voltage relative to battery bus, and ensure the input decoupling handles automotive load-dump up to the device's 58V rating.

Typical Applications
TLD60992ESXUMA1 is suitable for 6 applications: Automotive Headlamp LED Driver, Rear Combination Lamp LED Driver, Daytime Running Light (DRL) LED Driver, Industrial 24V LED Lighting Strip Driver, Agricultural and Construction Equipment Lighting, Architectural RGB-W LED Strip Driver.
Automotive Headlamp LED Driver
The TLD60992ESXUMA1 is purpose-built for automotive front lighting, where one IC drives both the low-beam and high-beam LED strings with independent PWM dimming. Its 4.5V to 58V input tolerates 12V cranking transients and 24V truck-bus load-dump, while the 2.2MHz switching frequency permits inductors small enough to fit inside a headlamp housing. The exposed-pad PG-TSDSO-24-5 package conducts MOSFET-driver heat into the headlamp's metal heat-sink bracket. Open-LED detection prevents output over-voltage when a high-beam LED disconnects, protecting downstream headlamp electronics.
Recommended
Rear Combination Lamp LED Driver
In rear combination lamps (tail / brake / indicator), the TLD60992ESXUMA1's two channels drive independent LED strings with different forward voltages and current ratings. The dual PWM inputs allow the indicator channel to flash at 1-2Hz while the tail channel holds constant brightness - both from a single controller. The wide 4.5V-58V input covers 12V and 24V commercial vehicle systems, and AEC-Q100 qualification plus over-temperature shutdown keep the part reliable inside the sealed rear-light enclosure, where ambient temperatures exceed 85C in summer sun.
Recommended
Daytime Running Light (DRL) LED Driver
DRL modules require high-efficiency DC-DC conversion to avoid wasting fuel as heat, and the TLD60992ESXUMA1's controller-based architecture pushes >90% efficiency at typical DRL currents. The SEPIC or boost topology configuration supports LED strings whose total forward voltage is higher than the 12V battery bus (typical for DRL with 6-12 series LEDs). The analog dimming input enables smooth brightness fade-in during ignition, a styling feature preferred by OEMs. PG-TSDSO-24-5 with thermal pad couples to the DRL housing for passive cooling.
Recommended
Industrial 24V LED Lighting Strip Driver
Industrial machinery, control panels, and warehouse fixtures often run on 24V DC rails and need multi-meter LED strips with constant-current regulation. The TLD60992ESXUMA1's flyback or buck configuration delivers a tightly regulated current through long LED chains, and its 58V input withstands the inductive spikes common in industrial cabinets. Dual channels support two separately controllable zones (work-area vs status indicators) from one IC. The exposed-pad package simplifies integration into IP-rated luminaires where PCB space is constrained.
Recommended
Agricultural and Construction Equipment Lighting
Tractors, excavators, and combines operate LED work-lamp arrays from 24V systems that see massive voltage transients when starter motors engage. The TLD60992ESXUMA1's 58V rating and -40C minimum operating temperature suit these harsh under-hood environments, while the dual channels allow two work lamps to be controlled independently (front vs rear). The AEC-Q100 qualification and IP-grade moisture tolerance extend field life. Internal open-LED protection is critical when vibration eventually disconnects a work-lamp connector.
Recommended
Architectural RGB-W LED Strip Driver
Architectural cove lighting uses RGB-W strips where one channel drives warm-white and another drives RGB color mix. The TLD60992ESXUMA1's two independent dimming inputs allow separate PWM for warm-white brightness and color-channel intensity. Operating from 24V or 48V architectural bus supplies up to 58V, the controller can be configured as a buck or SEPIC depending on the strip's forward voltage. The 2.2MHz switching frequency keeps the converter above the AM band, eliminating audible transformer noise in indoor installations.

Key Differentiators
- Multi-topology flexibility in one controller (vs TLD5097EPXUMA1)
- Dual-channel dimming per IC (vs TLD23313EPXUMA1)
- Switching efficiency above 90% (vs TLD1125ELXUMA1)
Design Notes
The exposed thermal pad (PG-TSDSO-24-5) must be soldered to a copper pour on the top layer of at least 200 mm^2, with thermal vias connecting to an inner ground plane. At 2.2MHz switching with external MOSFETs, gate-drive losses concentrate in the IC; insufficient thermal dissipation raises the junction above 125 C and triggers the internal thermal shutdown. The datasheet's reference layout shows a 4x4 via array under the pad.
Do not connect an inductor or transformer directly across VIN and SW without first verifying the topology. The TLD60992ESXUMA1 supports Buck, Boost, SEPIC, and Flyback, but each topology has unique external component requirements and current-sense polarity. The datasheet application circuit shows a distinct component arrangement per topology; substituting components designed for one topology into another circuit will cause regulation failure or MOSFET damage.
Estimated: at 12V VIN, 36V VOUT, 0.5A LED current with 85% efficiency, the controller drives approximately 1.76A average from the battery (12V*0.5A/0.85/36V*0.5A simplified). With an external MOSFET RDSon of 50 mOhms and 2.2 MHz switching, the MOSFET conduction and switching losses total approximately 0.5W. Choose a MOSFET rated for at least 80V VDS, 5A ID continuous, and RthJA below 50 C/W.
Keep the current-sense traces (CSP/CSN) as short as possible and route them as a differential pair directly from the sense resistor to the IC pins. Place the bootstrap capacitor (BST to SW) within 2mm of the IC. The high di/dt loop formed by input capacitor, MOSFET, and sense resistor must be minimized - use a tight layout with the input ceramic capacitor directly at the MOSFET drain to ground.
