Product details
Overview
LED6000PHR from STMicroelectronics is a monolithic step-down current source IC designed for high-brightness LED driving, delivering up to 3 A DC output current with ±3% accuracy, 4.5–61 V input range, and dedicated PWM dimming control via the DIM pin. It integrates an N-channel high-side MOSFET with 250 mΩ typical RDS,ON, supports adjustable switching frequency (250 kHz–1.5 MHz), and operates in low-dropout mode with 12 µs max. response.
For engineers reviewing the LED6000PHR datasheet, LED6000PHR pinout, LED6000PHR application, or LED6000PHR equivalent, key selection considerations include its HTSSOP16 exposed-pad thermal performance (RthJA = 40 °C/W), programmable current limit (0.68–4.7 A), soft-start timing control, VBIAS-assisted light-load efficiency, and synchronization capability for multi-device noise reduction.
Technical Context
The LED6000PHR implements voltage-mode PWM control with a fixed-frequency sawtooth oscillator whose slope is feedforward-compensated for stable gain across input voltage and switching frequency variations. Its error amplifier features 100 dB DC gain and 23 MHz GBWP, with FB referenced to a precise 0.250 V internal bandgap.
Dimming is implemented digitally via the DIM pin (1.23–1.7 V rising threshold), enabling PWM current modulation with timeout-based oscillator gating and automatic soft-start reinitiation after dim-off periods exceeding 42 ms. Thermal shutdown activates at 170 °C with 15 °C hysteresis, and overcurrent protection uses a programmable peak-current sense path tied to the ILIM pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output current | Up to 3 A DC with ±3% accuracy - enables stable high-power LED string biasing without external current-sense amplification. |
| Input voltage range | 4.5 V to 61 V - supports wide-input industrial and automotive LED systems, including 12/24/48 V rails and halogen replacement designs. |
| RDS,ON | 250 mΩ typ. - reduces conduction loss and thermal stress in the integrated high-side MOSFET, improving full-load efficiency. |
| Switching frequency | 250 kHz to 1.5 MHz (adjustable via FSW pin resistor) - allows optimization of magnetics size, EMI profile, and light-load efficiency trade-offs. |
| Dimming interface | Dedicated DIM pin with 1.23–1.7 V logic thresholds and 42 ms timeout - enables clean PWM dimming without microcontroller GPIO overhead or external timing circuitry. |
| Quiescent current | 2.4 mA typ. operating / 10 µA typ. shutdown - minimizes standby power in always-on lighting control systems. |
| Thermal protection | Auto-recovery thermal shutdown at 170 °C (15 °C hysteresis) - ensures robust operation under sustained overload or poor heatsinking conditions. |
Pinout & Package
LED6000PHR is housed in an HTSSOP16 package with exposed thermal pad (RthJA = 40 °C/W on ST demo board), requiring solder connection of the exposed pad to PCB ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VBIAS | Auxiliary supply input | Switches internal bias from VCC to external rail to reduce quiescent current at light load; bypass with 1 µF ceramic if used. |
| VIN (pins 2,3) | Main power input | High-current input path for 4.5–61 V supply; dual pins reduce trace resistance and improve thermal distribution. |
| VCC | Internal circuit supply | Filtered analog supply for control circuitry; requires 1 µF ceramic bypass to GND. |
| EN | Enable control | Active-high logic input (0.35–0.90 V ON threshold); internally pulled down if floating. |
| DIM | PWM dimming input | Accepts standard logic-level PWM signal; internal 2 µA pull-down enables direct MCU interface without external resistors. |
| LX (pins 13,14) | Power switch node | Drives external inductor; dual pins reduce parasitic inductance and improve current sharing in high-current paths. |
| BOOT | Bootstrap gate drive | Connects 100 nF capacitor to LX to generate gate voltage for internal high-side MOSFET. |
| GND (pin 16 + EP) | Signal and thermal reference | Exposed pad must be soldered to PCB ground plane for thermal conduction and low-impedance return path. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable current limitation | Peak current set from 0.68 A to 4.7 A via ILIM pin resistor - allows inductor RMS rating selection matched precisely to LED string requirements. |
| Synchronization capability | Master/slave SYNCH pin supports up to 5 devices - eliminates beat frequencies and reduces input ripple RMS in multi-channel LED systems. |
| VBIAS-assisted efficiency | Switches bias supply from VCC to auxiliary rail at light load - cuts operating IQ from 2.4 mA to 0.9–1.4 mA, extending battery life in portable lighting. |
| Low dropout operation | 12 µs max. response time - enables fast transient recovery during PWM dimming edges and maintains regulation under dynamic load steps. |
| Auto-recovery thermal shutdown | 170 °C trip with 15 °C hysteresis - prevents latch-up failure and enables self-resetting operation after cooling, improving system reliability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM3409HVMM/NOPB | External MOSFET driver (no integrated switch); 60 V max input; no VBIAS or synchronization pins. | Requires discrete high-side FET and gate driver; less compact layout but higher thermal flexibility. | Choose when board space allows discrete FET placement and thermal management is prioritized over integration. |
| TPS92692QPWPRQ1 | Integrated 3.5 A current source; 65 V input; I²C programmability; no DIM pin - uses analog/digital dimming via CTRL pin. | Supports closed-loop current calibration and diagnostics; lacks dedicated hardware PWM dimming pin and sync capability. | Choose when system-level telemetry, fault reporting, or fine-grained digital tuning outweighs need for simple hardware PWM control. |
Compared with LM3409HVMM/NOPB, LED6000PHR offers higher integration and simpler BOM but less thermal isolation; versus TPS92692QPWPRQ1, it provides deterministic hardware dimming and multi-device sync at the cost of configurability and diagnostics.

FAQ
What is the minimum recommended output capacitor value for stable operation?
The datasheet specifies that output capacitor selection must balance dimming performance and stability: smaller MLCC values (e.g., 10–22 µF) minimize current rise time and inductor overshoot during PWM dimming, while larger values risk oscillation. ST's evaluation board uses 22 µF × 2 in parallel, and the minimum effective capacitance is 10 µF with ESR ≤ 10 mΩ to ensure loop stability across all operating conditions.
Can the LED6000PHR drive LEDs with forward voltages exceeding 50 V?
Yes - the LED6000PHR regulates current, not voltage, and supports output voltages up to VIN – Vdropout. With 61 V max input and typical dropout of <1.5 V at 3 A, it can drive LED strings with total forward voltage up to ~59.5 V, provided the input supply exceeds the string VF by ≥1.5 V and thermal limits are observed.
How does the VBIAS pin improve efficiency at light load?
VBIAS supplies the internal analog circuitry independently from VCC, reducing quiescent current from 2.4 mA (VCC-only) to 0.9–1.4 mA. This occurs because VBIAS powers only essential bias circuits, bypassing the higher-current VCC LDO; efficiency gain is most pronounced below 20% load, where switching losses dominate.
Is the HTSSOP16 package RoHS and REACH compliant?
Yes - LED6000PHR is manufactured in ST's RoHS-compliant, lead-free HTSSOP16 package (Pb-free, halogen-free, and compliant with EU Directive 2011/65/EU and Regulation (EC) No 1907/2006 (REACH)). Full compliance documentation is available in ST's official product change notifications and material declarations.
