Product details
Overview
LED6001 from STMicroelectronics is a PWM-dimmable single-channel LED driver IC integrating a boost controller, high-side current sensing, and dual LDOs (3.3 V/5 V). It delivers constant-current regulation up to 60 V output with ±4% accuracy over temperature and production spread, supports boost/SEPIC/buck-boost topologies, and enables analog dimming (10:1) and enhanced PWM dimming via dedicated PWMI/PWMO pins - used in off-grid street lighting and emergency LED systems.
For engineers reviewing the LED6001 datasheet, LED6001 pinout, LED6001 application, or LED6001 equivalent, this page provides verified technical context on its peak-current-mode boost control, high-side sensing architecture, fault management (XFAULT open-drain), thermal shutdown with autorestart, and dual-dimming interface - critical for reliable high-brightness LED string design.
Technical Context
The LED6001 implements fixed-frequency peak-current-mode control with adjustable switching frequency (100 kHz–1 MHz) set via external resistor on FSW pin or synchronized externally. Its boost controller supports multiple topologies (boost, SEPIC, floating buck-boost) and features cycle-by-cycle MOSFET overcurrent protection via CSNS pin with 300–400 mV OCP threshold.
Current regulation uses high-side differential sensing across VFBP/VFBN (30–300 mV range) referenced to PGND/SGND, enabling robust short-to-ground protection when paired with a P-channel MOSFET. Fault detection includes output overvoltage (1.20 V OVFB threshold), open-load detection (−120 mV differential), and thermal shutdown at 150–175 °C with 40 °C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input voltage range | 5.5 V to 36 V - powers device and LDOs directly from wide-range DC supply without pre-regulation. |
| Output current sensing range | 30 mV to 300 mV differential - enables precise high-side current sensing with minimal power loss in sensing resistor. |
| Current reference accuracy | ±4% over −40 °C to +125 °C - ensures stable LED brightness across industrial temperature range and manufacturing variance. |
| Switching frequency | 100 kHz to 1 MHz (adjustable) - balances EMI, efficiency, and component size; fixed 600 kHz when FSW tied to LDO3. |
| Shutdown current | <10 µA at 25 °C - minimizes battery drain in emergency lighting during standby. |
| Fault signaling | XFAULT open-drain output - asserts low for overtemperature, output overvoltage, or LED overcurrent, simplifying host system monitoring. |
| Dimming interfaces | PWMI (enable + PWM input) and ADIM (0.3–1.2 V analog control) - support independent or combined dimming strategies. |
Pinout & Package
LED6001 is housed in HTSSOP-16 package with exposed thermal pad (electrically connected to PGND/SGND) for efficient heat dissipation in high-power LED applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PWMI | Enable & PWM dimming input | Dual-function digital input: ≥100 µs high pulse enables device and initiates soft-start; PWM duty cycle controls LED brightness. |
| FSW | Frequency setting/sync input | Resistor-to-SGND sets fSW; tied high to LDO3 fixes 600 kHz; accepts external sync clock 100–1000 kHz. |
| XFAULT | Fault indicator output | Open-drain output pulled low on thermal shutdown, OVFB trip, or LED overcurrent - requires external pull-up. |
| LDO3 | 3.3 V LDO output | Supplies internal logic and external circuitry; 30–46 mA current limit; UVLO thresholds at 2.2–3.0 V. |
| SGND | Analog ground reference | Return for COMP, ADIM, OVFB, CSNS - must be star-connected near IC to avoid noise coupling into sensing path. |
| COMP | Loop compensation node | Transconductance amplifier output; RC network to SGND stabilizes current loop for CCM operation above 50% duty. |
| ADIM | Analog dimming control | 0.3–1.2 V input linearly scales LED current reference; 260–280 mV turn-off threshold disables output. |
| OVFB | OVP feedback input | Monitors output voltage via resistor divider; trips at 1.20 V ±100 mV hysteresis to protect against open LED string. |
| CSNS | MOSFET current sense input | Connects to MOSFET source; detects switch OCP at 300–400 mV with slope compensation current injection. |
| PWMO | PWM dimming output | Drives external N-MOSFET in series with LED string; rise/fall times 50–120 ns / 30–60 ns into 3.3 nF load. |
| PGND | Power ground | Return for VDR, GATE, and CSNS; must connect close to MOSFET source resistor quiet terminal to minimize noise. |
| GATE | MOSFET gate driver output | Drives external N-channel power MOSFET; 3–6 Ω pull-up / 1–3 Ω pull-down resistance; 15–30 ns rise time. |
| VIN | Main supply input | Accepts 5.5–36 V; bypassed with 1 µF MLCC to PGND; powers both LDOs and internal circuitry. |
| VFBN / VFBP | High-side current sense inputs | Differential pair measuring voltage across external sense resistor; common-mode range up to 60 V. |
| TPAD | Thermal pad | Exposed pad electrically tied to PGND/SGND; requires solid copper pour for thermal performance and EMI reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated dual-LDO supply | On-chip 3.3 V (30 mA) and 5 V (75 mA) regulators eliminate external bias rails and reduce BOM count. |
| Topology flexibility | Native support for boost, SEPIC, and floating buck-boost configurations - adapts to varying input/output voltage relationships. |
| High-side current sensing | Enables P-MOSFET-based high-side switch configuration, providing inherent protection against LED+ short-to-ground faults. |
| Programmable soft-start | Fixed 2.9–4.5 ms internal soft-start prevents inrush current and stabilizes LED current ramp-up at turn-on. |
| Comprehensive fault coverage | Detects thermal overload, output overvoltage, LED overcurrent, open-load, and short-circuit - all reported via XFAULT. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS92691 | Current-mode boost controller with integrated 5-V gate driver; no onboard 3.3-V LDO; requires external bias for logic. | Lacks integrated analog dimming input - relies on external DAC or PWM-to-analog conversion. | Preferred when gate drive strength >1 A is needed and system already provides 3.3-V rail. |
| ON Semiconductor NCL30160 | Fixed-frequency boost controller with 0.5-A integrated MOSFET; no external MOSFET gate driver or high-side sensing. | Max 40-V output; not suitable for >60-V LED strings or topology flexibility requirements. | Selected for cost-sensitive, lower-power (<15 W) indoor lighting where external FET is unnecessary. |
Compared with TPS92691 and NCL30160, LED6001 uniquely integrates dual LDOs, high-side sensing, and dual-dimming interfaces in one HTSSOP-16 package - reducing external components while supporting higher output voltage and broader topology use cases.

FAQ
What is the maximum output voltage supported by LED6001?
LED6001 supports up to 60 V output voltage, enabled by its high-side differential current sensing architecture (VFBP/VFBN pins) with 65 V absolute maximum rating per pin. This allows driving longer LED strings in boost or SEPIC configurations without external level-shifting circuitry, provided external components (MOSFET, diode, inductor) are rated accordingly.
How does the LED6001 handle thermal overload?
LED6001 incorporates thermal shutdown with autorestart: when junction temperature exceeds 150–175 °C (typ. 160 °C), the device disables switching and pulls XFAULT low. After cooling below hysteresis threshold (~40 °C below trip), it automatically resumes operation without host intervention - ensuring robustness in enclosed luminaires or high-ambient environments.
Can LED6001 operate without an external MOSFET?
No - LED6001 is a controller-only IC with no integrated power switch. It requires an external N-channel MOSFET driven by the GATE pin (3–6 Ω pull-up/pull-down) and a separate N-MOSFET for PWM dimming controlled by PWMO. The IC provides gate drive capability, current sensing interface, and regulation logic but relies entirely on external power components.
What is the purpose of the TPAD thermal pad in HTSSOP-16?
The TPAD thermal pad is electrically connected to PGND and SGND and must be soldered to a large PCB copper pour for effective heat dissipation. It reduces junction-to-ambient thermal resistance to 45 °C/W (2s2p layout), critical for sustaining full-load operation at elevated ambient temperatures. Improper thermal pad connection risks thermal shutdown or reduced lifetime.
