Product details
Overview
TLD5098EPXUMA1 from Infineon Technologies is a multitopology DC/DC controller IC designed for LED driver applications in automotive environments. It supports boost, buck, buck-boost, SEPIC, and flyback configurations with fixed-current or fixed-voltage regulation, 4.5 V to 45 V input range, 100–500 kHz adjustable switching frequency, and integrated analog/PWM dimming.
For engineers reviewing the TLD5098EPXUMA1 datasheet, TLD5098EPXUMA1 pinout, TLD5098EPXUMA1 application, or TLD5098EPXUMA1 equivalent, this device offers current-mode control, low-side n-channel MOSFET gate drive, open-circuit/short-to-GND/overvoltage/overtemperature protection, and AEC-Q100 qualification - critical for automotive lighting design validation.
Technical Context
The TLD5098EPXUMA1 implements current-mode control with slope compensation and leading-edge blanking for stable loop response across topologies. Its internal 5 V LDO powers gate drivers and bias circuitry, while the SWCS pin senses switch current via a 300 mV threshold for cycle-by-cycle peak current limiting.
It features dual feedback paths: FBH/FBL for output voltage regulation and OVFB for overvoltage protection with external resistive divider setting. The FREQ/SYNC pin enables either resistor-set oscillator operation (250–500 kHz) or synchronization to external clock signals within ±10% capture range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 45 V - supports full automotive battery range including cold-crank and load-dump transients. |
| Switching Frequency | 100 kHz to 500 kHz - adjustable via external resistor or synchronizable to external clock for EMI reduction. |
| Gate Driver Peak Current | 380 mA sourcing / 550 mA sinking - drives low-side n-channel MOSFETs with fast turn-on/turn-off in high-current LED applications. |
| Current Sense Threshold | 300 mV - enables accurate, temperature-stable peak current detection at SWCS pin for reliable overcurrent protection. |
| Shutdown Current | < 10 µA - ultra-low IQ_OFF during EN deactivation minimizes standby power in always-on vehicle systems. |
| Operating Junction Temp | −40 °C to +150 °C - qualified per AEC-Q100 Grade 1 for under-hood automotive deployment. |
| Protection Functions | Open-circuit, short-to-GND, overvoltage, overtemperature - autonomous fault detection with diagnostic flag output via EN/PWMI pin. |
Pinout & Package
Package: PG-TSDSO-14 (14-pin thermally enhanced exposed-pad SOIC), RoHS-compliant, optimized for automotive thermal cycling and PCB-level heat dissipation via EP connection to inner GND layer.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 IVCC | Internal LDO output | Supplies 5 V bias for internal logic and gate drivers; requires local ceramic bypass capacitor. |
| 2 SWO | Switch gate driver output | Drives gate of external low-side n-channel MOSFET; rated for 380 mA peak source / 550 mA sink. |
| 3 SGND | Current sense ground | Dedicated Kelvin return for SWCS sensing path to avoid noise coupling into current regulation loop. |
| 4 SWCS | Switch current sense input | Monitors MOSFET source current via shunt; triggers cycle-by-cycle shutdown at 300 mV threshold. |
| 5 PWMO | PWM dimming output | Drives external MOSFET for LED string disconnection or PWM current shaping; open-drain compatible. |
| 6 FBH | Voltage feedback (+) | Non-inverting input of error amplifier; used with FBL to set regulated output voltage in buck/boost topologies. |
| 7 FBL | Voltage feedback (−) | Inverting input of error amplifier; forms differential feedback pair with FBH for precise regulation. |
| 8 COMP | Compensation network node | Connects external RC network to stabilize control loop; determines phase margin and transient response. |
| 9 OVFB | Overvoltage protection input | Accepts resistive divider output; trips protection when sensed voltage exceeds internal 1.25 V reference. |
| 10 SET | Analog dimming control | Sets LED current reference via external voltage (0–IVCC); unused pin must be tied to IVCC. |
| 11 FREQ/SYNC | Oscillator control | Resistor-to-GND sets frequency; external clock signal (100–500 kHz) enables synchronization for multi-phase designs. |
| 12 GND | Power ground | Main system ground return; separate from SGND to prevent current-sense interference. |
| 13 EN/PWMI | Enable or PWM input | Logic HIGH enables IC; PWM signal here provides direct analog-compatible dimming control. |
| 14 IN | Main supply input | Connects to 4.5–45 V automotive rail; powers internal LDO and supplies energy to switching stage. |
| EP | Exposed thermal pad | Must be soldered to inner-layer GND plane with ≥6 thermal vias for junction-to-board thermal resistance ≤35 K/W. |
Key Features
| Feature | Design Value |
|---|---|
| Multitopology support | Configurable as boost, buck, buck-boost, SEPIC, or flyback via external component selection - eliminates need for multiple controller SKUs. |
| Integrated protection suite | Autonomous open-circuit, short-to-GND, overvoltage, and overtemperature detection with latched or auto-retry behavior per configuration. |
| Soft-start function | Internally controlled ramp limits inrush current and output voltage overshoot during startup - no external timing components required. |
| Dual dimming interface | Simultaneous analog (SET pin) and PWM (EN/PWMI or PWMO) dimming paths enable flexible brightness control in headlight and DRL systems. |
| Thermally robust package | PG-TSDSO-14 with exposed pad achieves RthJA ≤ 45 K/W on 2-layer board - sustains 150 °C junction temperature in compact automotive modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20051ATP/V+T | Fixed-frequency 2.2 MHz buck controller; no multitopology support; integrated high-side MOSFET; no analog dimming. | Limited to buck-only LED drivers; lacks open-circuit/short-to-GND diagnostics; suited for space-constrained interior lighting only. | Select when board area is critical and topology is fixed buck with <1 A output. |
| LM34927QMH/NOPB | Adjustable 50–1000 kHz buck-boost controller; no integrated protection diagnostics; requires external current sense amplifier. | No AEC-Q100 qualification; lacks overvoltage/overtemperature reporting; requires additional ICs for full automotive fault coverage. | Select for non-automotive industrial LED drivers where cost is prioritized over integrated safety functions. |
Compared with MAX20051ATP/V+T and LM34927QMH/NOPB, the TLD5098EPXUMA1 uniquely combines multitopology flexibility, AEC-Q100 qualification, and autonomous protection - enabling single-part solutions for exterior lighting across OEM platforms without redesign.

FAQ
What topologies does the TLD5098EPXUMA1 support?
The TLD5098EPXUMA1 supports boost, buck, buck-boost, SEPIC, and flyback configurations by reconfiguring external passive components - no internal register programming required. Each topology maintains current-mode control stability using the same COMP compensation network and SWCS current-sense interface.
How is overvoltage protection implemented?
Overvoltage protection uses the OVFB pin connected to a resistive divider across the output. When the divided voltage exceeds the internal 1.25 V reference, the IC disables switching and asserts a fault flag via EN/PWMI pin. Recovery is automatic after fault removal and soft-start reset.
Can the TLD5098EPXUMA1 drive high-side MOSFETs?
No - the TLD5098EPXUMA1 drives only low-side n-channel MOSFETs via its SWO output. Its internal architecture and gate driver design are optimized for low-side switching; high-side drive requires external level-shifting circuitry not supported by this IC.
What is the role of the SGND pin?
SGND is a dedicated current-sense ground pin providing a Kelvin return path for the SWCS pin. It isolates high-di/dt switch current return from main power ground, preventing noise injection into the 300 mV current-sense comparator and ensuring accurate peak-current limiting.
