Product details
Overview
HVLED002 from STMicroelectronics is a high-performance current-mode LED controller IC designed for off-line and DC-DC fixed-frequency LED driver topologies. It delivers precise 250 kHz oscillator frequency, latching PWM cycle-by-cycle current limiting, and a high-current totem pole output (±1 A peak) to drive N-channel MOSFETs in constant-current LED regulation circuits - used in industrial LED lighting ballasts and secondary-side buck regulators.
For engineers reviewing the HVLED002 datasheet, HVLED002 pinout, HVLED002 application, or HVLED002 equivalent, this page provides verified technical context, SO-8 package mapping, real-world timing and current-sense behavior, and validated alternative options for LED driver design continuity.
Technical Context
The HVLED002 implements a trimmed internal oscillator with guaranteed 250 kHz operation at 25 °C and supports up to 500 kHz via RT/CT programming. Its current-mode architecture uses ISENSE input with programmable threshold (MAXCS = 267 mV typ.) derived from COMP voltage, enabling accurate peak-current control without external sensing offsets.
It integrates an error amplifier with 2.5 V reference (±2%), 90 dB open-loop gain, and 1 MHz unity-gain bandwidth; a precision 5.00 V ±5 mV VREF output capable of sourcing >20 mA; and undervoltage lockout with 8.4 V turn-on / 7.6 V turn-off hysteresis - all optimized for stable, low-noise LED current regulation in wide-input-voltage applications (8.4–30 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Oscillator frequency | 250 kHz guaranteed at 25 °C; supports up to 500 kHz via RT/CT tuning - enables precise duty-cycle control in high-efficiency LED drivers. |
| Output drive capability | ±1 A peak totem pole output - directly drives N-channel MOSFET gates without external buffers in high-current LED applications. |
| VREF accuracy | 5.00 V ±5 mV at 1 mA load - supplies stable bias for RT/CT timing network and auxiliary circuitry (e.g., microcontrollers). |
| Current sense threshold | 267 mV max (MAXCS), with 3 V/V gain from COMP - enables accurate shunt-based peak-current detection with minimal power loss. |
| UVLO thresholds | Turn-on at 8.4 V, turn-off at 7.6 V - ensures reliable startup and shutdown across wide input ranges (8.4–30 V Vi). |
| Error amplifier reference | 2.50 V ±2% non-inverting input - forms stable feedback node for LED current regulation loop compensation. |
| Start-up current | 0.5 mA max - minimizes auxiliary supply burden during cold-start in isolated LED driver designs. |
Pinout & Package
The HVLED002 is housed in an SO-8 surface-mount package (ECOPACK® compliant), with exposed pad not electrically connected. Thermal resistance junction-to-ambient is 150 °C/W, supporting operation from –40 °C to +150 °C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (COMP) | Error amplifier output | Provides open-loop compensation node; sinks ≥2 mA, sources ≥0.5 mA - used for loop stability tuning in current-regulated LED drivers. |
| 2 (VFB) | Error amplifier inverting input | Connects to LED current-sense feedback divider; referenced to internal 2.5 V - sets regulated LED current level. |
| 3 (ISENSE) | Current sense comparator input | Accepts shunt voltage; threshold dynamically set by COMP (VCS = 1/3 × (VCOMP − 1.4 V)) - enables cycle-by-cycle overcurrent protection. |
| 4 (RT/CT) | Oscillator timing interface | RT resistor to VREF and CT capacitor to GND program frequency and max duty cycle - supports fixed-frequency or fixed-off-time topologies. |
| 5 (GROUND) | Signal and power ground reference | Single-point ground for analog and power sections - critical for noise immunity in high-dv/dt LED switching environments. |
| 6 (OUTPUT) | Gate driver output | ±1 A peak totem pole stage - directly switches N-MOSFET gate; low-state during UVLO ensures safe FET turn-off. |
| 7 (Vi) | Supply input | Operates from 8.4 V to 30 V - powers internal circuitry and enables direct connection to rectified AC or DC bus in off-line LED drivers. |
| 8 (VREF) | Precision reference output | 5.00 V ±5 mV, >20 mA capable - supplies timing network and optional microcontroller; requires 0.1 µF ceramic bypass to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Latching PWM current limit | Enables cycle-by-cycle protection without external latch circuitry - prevents MOSFET failure during LED short-circuit or thermal overload. |
| Internally trimmed 5 V reference | Stable 5.00 V ±5 mV output with <0.2 mV/°C drift - eliminates need for external reference in cost-sensitive LED driver BOMs. |
| Leading edge blanking support | Compatible with RC or active LEB circuits on ISENSE - suppresses gate-drive-induced current spikes for clean MOSFET turn-on detection. |
| High-current totem pole output | ±1 A peak drive with 50 ns rise/fall times (CL = 1 nF) - reduces external gate resistor requirements and switching losses in high-frequency LED drivers. |
| Undervoltage lockout with hysteresis | 8.4 V turn-on / 7.6 V turn-off window - prevents erratic operation during brown-out or soft-start conditions in unregulated input rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LED controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UCC28810 | Fixed 60–100 kHz frequency; no programmable RT/CT; integrated 600 V MOSFET driver; lacks VREF output. | Designed for primary-side flyback LED drivers; not suitable for secondary-side buck or VREF-powered MCU integration. | Select when primary-side regulation and higher integration are prioritized over frequency flexibility and auxiliary power capability. |
| NCP1075 | Fixed 65 kHz frequency; no current-mode sensing; requires external current sense amp; 500 mA output drive. | Targeted at low-cost, low-power LED bulbs (<15 W); lacks cycle-by-cycle limiting and high-current gate drive. | Choose only for cost-sensitive, low-power applications where 250 kHz operation and ±1 A drive are unnecessary. |
Compared with UCC28810 and NCP1075, HVLED002 uniquely combines programmable 250 kHz oscillator, ±1 A gate drive, and 5 V/20 mA VREF output - making it optimal for high-efficiency, medium-power secondary-side LED drivers requiring design flexibility and auxiliary power integration.

FAQ
What is the maximum operating frequency of HVLED002?
The HVLED002 supports up to 500 kHz oscillator frequency using external RT/CT components. Its trimmed internal oscillator guarantees 250 kHz at 25 °C, and Figure 4 in the datasheet shows RT vs. fOSC curves confirming operation beyond 400 kHz with appropriate timing networks.
How does HVLED002 implement cycle-by-cycle current limiting?
HVLED002 uses latching PWM: the ISENSE pin compares shunt voltage against a COMP-derived threshold (VCS = 1/3 × (VCOMP − 1.4 V)). When exceeded, the OUTPUT pin immediately goes low and remains latched until the next oscillator cycle - ensuring per-cycle overcurrent protection without external logic.
Can HVLED002 drive a P-channel MOSFET directly?
No - HVLED002's OUTPUT pin is a totem pole stage designed to sink and source current for N-channel MOSFET gate driving. Its low-state during UVLO and active-low default behavior make it unsuitable for direct P-MOSFET control without level-shifting circuitry.
Is external compensation required for the error amplifier?
Yes - pins 1 (COMP) and 2 (VFB) are exposed for external loop compensation. The error amplifier has 90 dB open-loop gain and 1 MHz bandwidth; typical designs use Type II or III networks across COMP and VFB to stabilize the current regulation loop per application requirements.
