Product details
Overview
TLD6098-1EP from Infineon is a single-channel, multi-topology DC-DC controller for LED driver applications, supporting buck, boost, and buck-boost configurations with up to 70 V output voltage, ±3.5% LED current accuracy, and integrated PMOS dimming gate driver. It operates across 100–500 kHz switching frequency (synchronizable to 2.2 MHz) and includes overvoltage, short-to-ground, overcurrent, open-feedback, and overtemperature diagnostics - deployed in automotive front/rear lighting modules.
For engineers reviewing the TLD6098-1EP datasheet, TLD6098-1EP pinout, TLD6098-1EP application, or TLD6098-1EP equivalent, key selection criteria include its rail-to-rail current sense amplifier enabling >20-white-LED string support, analog-adjustable current regulation via SET pin, spread-spectrum modulation for EMC compliance, and embedded 10-bit PWM engine (150–750 Hz, 0–100% duty) controlled by DC/PWMI.
Technical Context
The device implements peak-current-mode control with internal slope compensation to suppress sub-harmonic oscillation above 50% duty cycle. Its rail-to-rail current sense amplifier enables flexible topology selection while maintaining accurate current regulation across wide output voltage ranges (up to 70 V).
Switching frequency is set by an external resistor on FREQ/SYNC/SPREAD or synchronized to an external clock (low- or high-frequency mode), and spread-spectrum modulation is integrated to reduce EMI peaks. The embedded PWM engine generates dimming signals with 10-bit resolution and programmable frequency, driven directly by analog voltage or digital PWM on DC/PWMI.

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX20078ATP/V+ (Analog Devices) | Single-channel buck controller with 4.5–65 V input, no integrated spread spectrum or embedded PWM engine; requires external dimming IC. | Limited to buck-only topology; lacks differential FBH/FBL sensing and analog SET adjustment. | Select when cost-sensitive buck-only designs prioritize simplicity over multi-topology flexibility and integrated dimming. |
| TPS92692QPWPRQ1 (TI) | High-accuracy LED controller (±1.5% current) with integrated N-channel gate driver, but no PMOS dimming output or spread-spectrum capability. | Optimized for high-precision constant-current regulation only; no built-in fault reporting or analog dimming interface. | Select when ultra-high current accuracy is mandatory and external fault management is acceptable. |
Compared with MAX20078ATP/V+ and TPS92692QPWPRQ1, TLD6098-1EP uniquely combines multi-topology support, embedded 10-bit PWM dimming, spread-spectrum EMI reduction, and comprehensive diagnostics - making it optimal for ASIL-B-compliant automotive lighting where integration, reliability, and EMC robustness are critical.

FAQ
What topologies does the TLD6098-1EP support?
The TLD6098-1EP supports buck, boost, and buck-boost configurations via external power stage selection. Its rail-to-rail current sense amplifier and differential FBH/FBL inputs enable stable operation across all three topologies, with output voltage capability up to 70 V in boost mode and input voltage tolerance up to 58 V.
How is LED current accuracy maintained over temperature?
LED current accuracy is ±3.5% over the full operating temperature range (−40°C to +150°C junction), achieved through internal calibration, slope-compensated peak-current-mode control, and rail-to-rail current sensing - no external trimming or temperature compensation circuitry required.
Can the TLD6098-1EP drive both the main switching MOSFET and a dimming PMOS simultaneously?
Yes: SWO drives the external n-channel power switch (e.g., for boost/buck power stage), while PWMO independently drives an external p-channel MOSFET for LED dimming and protection. Both outputs operate concurrently with coordinated timing to prevent shoot-through and ensure safe dimming transitions.
What fault conditions trigger the FPWM/FAULT pin?
The FPWM/FAULT pin asserts high during overvoltage (FBH/FBL threshold exceeded), short-to-ground (detected via SWCS), overcurrent (peak current limit exceeded), open feedback (no voltage on FBH/FBL), or overtemperature (junction >150°C). Each fault condition is latched and requires reset via IN supply cycling or EN_INT deassertion.
