Product details
Overview
HVLED805TR from STMicroelectronics is an off-line LED driver IC integrating an 800 V avalanche-rugged power MOSFET and a current-mode PWM controller for quasi-resonant flyback topology. It delivers ±5% constant LED output current via primary-sensing feedback, eliminates optocoupler and secondary-side sensing, and supports both constant-current (CC) and constant-voltage (CV) regulation - enabling safe operation during LED string open/short faults in retrofit lamp designs.
For engineers reviewing the HVLED805TR datasheet, HVLED805TR pinout, HVLED805TR application, or HVLED805TR equivalent, key selection criteria include primary-sensed CC accuracy, integrated 800 V MOSFET ruggedness, QR ZVS operation, mains-independent regulation via voltage feed-forward, and open/short LED string protection behavior.
Technical Context
The HVLED805TR implements a current-mode quasi-resonant flyback controller with transformer demagnetization detection on the DMG pin to enable zero-voltage switching. Its internal 800 V MOSFET features 11 Ω RDS(on) at 25 °C and 50 mJ single-pulse avalanche energy rating, supporting direct rectified-mains operation without external HV startup components.
Regulation combines primary-sensed CC control (via ILED reference and peak current limiting) and CV control (using sampled DMG voltage as error amplifier input), both stabilized by line-voltage feed-forward through the same DMG pin. Protection includes hiccup-mode OCP triggered at 1 V across Rsense, brownout detection, and automatic restart after fault clearance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Integrated MOSFET V(BR)DSS | 800 V minimum - enables direct connection to rectified universal AC input (85–265 VAC) without external HV switch. |
| Constant Current Accuracy | ±5% - achieved via primary-sensing architecture eliminating optocoupler drift and secondary-side component tolerances. |
| Switching Topology | Quasi-resonant ZVS flyback - reduces switching losses and EMI by triggering MOSFET turn-on at transformer demagnetization valley. |
| Max Switching Frequency | 166 kHz top-limited - prevents excessive frequency rise at light load/high line while maintaining ZVS proximity. |
| Protection Features | Hiccup-mode OCP, open/short LED management, brownout detection, auxiliary winding disconnect - all auto-restart with no latch-up. |
| Startup Method | Internal HV start-up circuit - draws 5.5 mA typical from drain to charge VCC, enabling self-supply even during CC regulation when auxiliary winding voltage drops. |
| Feed-forward Support | Voltage feed-forward via DMG pin - compensates for mains variation in CC regulation, ensuring stable LED current across 85–265 VAC input range. |
Pinout & Package
HVLED805TR is housed in a SO16N (Small Outline, 16-pin, narrow-body) package with exposed drain pads (pins 13–16) thermally connected to the internal MOSFET die for enhanced heat dissipation. The copper area under drain pins must be designed per ST's mechanical recommendations (Doc ID 18077, Section 6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 SOURCE | MOSFET source & current sense input | Connects to Rsense; senses peak drain current for CC regulation and OCP; includes 250 ns leading-edge blanking for noise immunity. |
| 3 VCC | Supply voltage input | Powered by internal HV start-up generator or auxiliary winding; UVLO thresholds at 12 V (turn-on) and 10.5 V (restart); bypass capacitor required. |
| 4 GND | Signal and gate-drive return | Common ground for control logic and gate driver; must be isolated from high-dI/dt return paths to avoid noise coupling. |
| 5 ILED | CC regulation reference node | External capacitor sets dynamic reference for peak current limit; voltage automatically adjusted to maintain average LED current constant. |
| 6 DMG | Demagnetization detection & feed-forward input | Detects transformer valley for QR turn-on; samples output voltage for CV regulation; monitors input voltage for feed-forward - all via single pin. |
| 7 COMP | Error amplifier output | Drives external RC compensation network; determines operating mode (QR/valley-skipping/burst) based on voltage level (e.g., <1 V triggers burst mode). |
| 8–11 N.A. | No internal connection | Must remain unconnected; no routing or copper pour allowed. |
| 12 N.C. | Not internally connected | Provides creepage/clearance margin on PCB; electrically floating. |
| 13–16 DRAIN | MOSFET drain & HV start-up sink | Connects to rectified mains input; carries full switching current; thermal pad tied to internal MOSFET frame for heatsinking. |
Key Features
| Feature | Design Value |
|---|---|
| Primary-sensing CC regulation | Eliminates optocoupler, secondary shunt regulator, and current-sense resistor - reducing BOM count, cost, and failure points in LED lamps. |
| Integrated 800 V avalanche-rugged MOSFET | Withstands surge transients and inductive kickback without external snubber; rated for 50 mJ single-pulse avalanche energy at Tj = 25 °C. |
| Multi-mode operation (QR / valley-skipping / burst) | Optimizes efficiency across full load range: QR at heavy load, valley-skipping at medium load, burst mode below 10% load - meeting ERP Tier 2 standby requirements. |
| Single-pin dual-function DMG interface | Performs demagnetization detection, output voltage sampling, and input voltage feed-forward - simplifying transformer design and PCB layout. |
| Automatic self-supply from rectified mains | Re-engages HV start-up generator when VCC falls below 10.5 V, sustaining operation during CC regulation when auxiliary winding voltage collapses. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar off-line primary-sensing LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MP1601GQ-Z | Integrates 650 V MOSFET; lacks built-in HV start-up; requires external startup resistor; ±8% CC accuracy. | Targeted at lower-cost, lower-power (<15 W) LED bulbs; no CV regulation mode; limited surge robustness. | Select when BOM cost is critical and input voltage is limited to ≤230 VAC; verify external startup design and thermal derating. |
| NCL30002DR2G | 800 V MOSFET; fixed-frequency (up to 130 kHz) rather than QR; no valley-skipping; ±6% CC accuracy. | Designed for simpler, lower-EMI applications where ZVS benefits are secondary; no burst-mode - higher no-load power. | Select for designs prioritizing predictable EMI profile and layout simplicity over peak efficiency; confirm thermal margin at full load. |
Compared with MP1601GQ-Z and NCL30002DR2G, HVLED805TR uniquely combines 800 V ruggedness, QR ZVS, multi-mode efficiency optimization, and dual CC/CV regulation in one SO16N package - making it optimal for high-reliability, globally rated LED retrofit lamps requiring minimal external components.

FAQ
What is the purpose of the DMG pin in HVLED805TR?
The DMG pin serves three simultaneous functions: detecting transformer demagnetization for quasi-resonant zero-voltage switching, sampling output voltage for constant-voltage regulation, and monitoring input voltage for mains-independent constant-current regulation. It uses internal clamping (−60 mV to +3.3 V) and blanking logic to ensure reliable operation across line and load conditions without external capacitors.
Does HVLED805TR require an external startup resistor?
No. HVLED805TR integrates a high-voltage startup generator that draws current directly from the DRAIN pin to charge the VCC capacitor. This eliminates the need for an external high-voltage startup resistor, reducing component count and improving reliability in compact LED lamp designs.
How does HVLED805TR handle LED string open-circuit failures?
When the LED string opens, HVLED805TR automatically transitions from constant-current to constant-voltage regulation using the sampled DMG voltage as feedback. This limits output voltage to a safe level, preventing overvoltage damage to downstream components and enabling graceful fail-safe behavior required in certified lighting products.
What is the maximum recommended PCB copper area under drain pins 13–16?
STMicroelectronics recommends a minimum copper pour of 120 mm² (e.g., 10 mm × 12 mm) under drain pins 13–16, connected to internal MOSFET thermal frame via multiple vias (≥4 × 0.3 mm diameter). This achieves the specified RthJA of 110 °C/W and ensures safe operation at 0.9 W power dissipation in free-air conditions.
