Product details
Overview
TLD5095ELXUMA1 from Infineon Technologies is a smart LED boost controller IC designed for automotive lighting systems, featuring integrated status pin for fault reporting, 4.75–45 V input voltage range, constant-current LED regulation, and flexible 100–500 kHz switching frequency. It supports Boost-to-Battery topology and delivers diagnostic capability in headlamp and DRL applications.
For engineers reviewing the TLD5095ELXUMA1 datasheet, TLD5095ELXUMA1 pinout, TLD5095ELXUMA1 application, or TLD5095ELXUMA1 equivalent, key selection criteria include status-pin logic behavior, thermal performance in PG-SSOP-14 exposed pad package, overvoltage protection threshold, analog vs. PWM dimming support, and compatibility with Boost-to-Ground versus Boost-to-Battery configurations.
Technical Context
The TLD5095ELXUMA1 implements a current-mode DC-DC boost controller with internal high-side switch driver, fixed-frequency PWM control, and real-time fault detection via open-drain STATUS pin. It regulates LED string current using external sense resistor feedback and supports both constant-current and constant-voltage modes.
Its architecture includes cycle-by-cycle current limiting, thermal shutdown, output overvoltage protection (OVP), and undervoltage lockout (UVLO) at 4.75 V. The device operates across automotive battery transients and is qualified per AEC-Q100 Grade 1 (−40 °C to +125 °C ambient).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.75 V to 45 V - supports full automotive battery range including cold-crank (4.75 V) and load-dump (45 V) conditions. |
| Switching Frequency | 100 kHz to 500 kHz - adjustable via external resistor; enables EMI optimization and inductor size reduction. |
| LED Current Regulation | Constant-current mode only - accuracy ±5% over temperature and line; set by external sense resistor. |
| OVP Threshold | Typ. 60 V - protects downstream LEDs and MOSFETs during open-load or feedback fault. |
| STATUS Pin Function | Open-drain fault indicator - pulls low on overtemperature, OVP, UVLO, or oscillator fault; requires external pull-up. |
| Operating Ambient Temp | −40 °C to +125 °C - AEC-Q100 Grade 1 qualified for under-hood and exterior lighting placement. |
Pinout & Package
Package: PG-SSOP-14-1 (exposed thermal pad), RoHS-compliant, moisture sensitivity level MSL3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| SW | Switch node | Drives external high-side N-channel MOSFET gate; connects to boost inductor and diode anode. |
| FB | Feedback input | Monitors LED current via external sense resistor; sets regulation point for constant-current loop. |
| CTRL | Frequency and dimming control | Resistor-connected pin sets switching frequency; also accepts PWM signal for digital dimming. |
| STATUS | Fault indicator output | Open-drain output asserted low during thermal shutdown, OVP, UVLO, or oscillator failure. |
| EN | Enable input | Active-high logic input; must be ≥2.0 V to enable operation; internal pull-down when floating. |
Key Features
| Feature | Design Value |
|---|---|
| Status pin with fault classification | Single-pin open-drain output distinguishes thermal, overvoltage, and supply faults-enables system-level diagnostics without additional sensors. |
| Wide input voltage tolerance | 4.75–45 V operation covers 12 V and 24 V automotive systems, including cranking and load-dump stress events. |
| Configurable switching frequency | 100–500 kHz adjustment via single external resistor allows layout-specific EMI mitigation and magnetics optimization. |
| Integrated protection suite | Combines UVLO, cycle-by-cycle current limit, thermal shutdown, and output OVP-reduces need for discrete protection components. |
Applications
| Automotive Headlamps | Daytime Running Lights (DRL) |
|---|---|
Use Scenario: High-brightness LED arrays in adaptive front-lighting systems requiring precise current regulation and fault reporting. IC Role / Device Role / Timing Role: Primary boost controller managing LED string current and communicating thermal/OVP faults to MCU via STATUS pin. Use Value: Enables ASIL-B compatible lighting designs through deterministic fault signaling and AEC-Q100 qualification. | Use Scenario: Compact, thermally constrained LED modules mounted in bumper or grille requiring stable current under wide battery voltage swings. IC Role / Device Role / Timing Role: Constant-current boost regulator with integrated OVP and UVLO-eliminates need for external supervisor ICs. Use Value: Reduces BOM count by integrating protection functions while maintaining ±5% current accuracy across −40 °C to +125 °C. |
| Interior Ambient Lighting | LED Fog Lamps |
Use Scenario: Low-power, dynamically dimmed cabin lighting where PWM dimming coexists with analog brightness control signals. IC Role / Device Role / Timing Role: Boost controller accepting PWM input on CTRL pin for flicker-free dimming; STATUS pin reports overtemperature during sustained high-brightness operation. Use Value: Supports seamless transition between static and dynamic lighting modes without external dimming interface ICs. | Use Scenario: High-reliability fog lamps operating in humid, vibration-prone environments with frequent on/off cycling. IC Role / Device Role / Timing Role: Regulates LED current in Boost-to-Ground configuration; STATUS pin flags open-circuit LED string failures during self-test sequences. Use Value: Improves field reliability by enabling early detection of LED degradation before complete failure occurs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LED boost controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AL8862SP-13 | Fixed 500 kHz switching frequency; no STATUS pin; requires external OVP circuit. | Lacks integrated fault reporting-suitable only where MCU-based diagnostics are already implemented. | Select when cost-sensitive designs omit diagnostic requirements and accept added external components for protection. |
| LM3409QMY/NOPB | Adjustable frequency (200–2000 kHz); no integrated STATUS pin; supports high-side current sensing only. | Requires external comparator for fault signaling; lacks AEC-Q100 qualification. | Prefer for non-automotive industrial LED drivers where qualification and diagnostic integration are not mandatory. |
Compared with AL8862SP-13 and LM3409QMY/NOPB, the TLD5095ELXUMA1 provides integrated fault signaling, AEC-Q100 qualification, and wider input range-making it uniquely suitable for safety-critical automotive lighting where diagnostic coverage and transient robustness are required.

FAQ
What is the function of the STATUS pin on TLD5095ELXUMA1?
The STATUS pin is an open-drain output that asserts low during detected fault conditions-including overtemperature, output overvoltage, input undervoltage lockout, or oscillator failure. It requires an external pull-up resistor and enables direct connection to a microcontroller GPIO for real-time system-level fault monitoring without additional circuitry.
Can TLD5095ELXUMA1 operate in SEPIC topology?
Yes, the TLD5095ELXUMA1 supports SEPIC configuration per Infineon's application documentation. Its current-mode control architecture and flexible feedback structure allow stable operation in SEPIC, Boost-to-Ground, and Boost-to-Battery topologies-enabling design reuse across different LED voltage and grounding requirements.
Does TLD5095ELXUMA1 support analog dimming like TLD5098EL?
No. The TLD5095ELXUMA1 does not support analog dimming. It features a dedicated STATUS pin for diagnostics, whereas analog dimming (average LED current adjustment) is exclusive to the TLD5098EL variant. Dimming on TLD5095ELXUMA1 is implemented via PWM signal applied to the CTRL pin.
What thermal management considerations apply to the PG-SSOP-14 package?
The PG-SSOP-14 package includes an exposed thermal pad that must be soldered to a minimum 100 mm² copper pour on the PCB for effective heat dissipation. Thermal resistance θJA is 45 °C/W with proper layout; insufficient pad area or missing vias increases junction temperature and may trigger thermal shutdown under continuous 1 A LED current loads.
