Product details
Overview
HVLED815PFTR from STMicroelectronics is a high-voltage, integrated primary-side regulated (PSR) LED driver IC combining an 800 V avalanche-rugged 6 Ω Power MOSFET and a quasi-resonant PWM controller in a single SO-16N package. It delivers ±3% constant LED current accuracy, >0.9 power factor, and open/short LED string protection for offline AC-DC LED drivers up to 15 W.
For engineers reviewing the HVLED815PFTR datasheet, HVLED815PFTR pinout, HVLED815PFTR application, or HVLED815PFTR equivalent, this device supports high-efficiency, optocoupler-free LED bulb replacement designs with primary sensing, QR flyback operation, and self-supply capability across universal AC input.
Technical Context
The HVLED815PFTR implements primary-sensing regulation (PSR) using demagnetization detection on the auxiliary winding to achieve both constant-current (CC) and constant-voltage (CV) regulation without secondary-side feedback components. Its internal 800 V MOSFET enables direct rectified-mains operation with valley-skipping and burst-mode control for light-load efficiency.
It integrates a high-voltage startup generator (40–60 V turn-on threshold, 5.5 mA typical charge current), programmable leading-edge blanking (6–30 µs), and dual-clamped DMG input (−60 mV to +3.3 V) for robust transformer demagnetization sensing. The CS pin combines current sensing and line feedforward via external ROS/RPF resistors to maintain high power factor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 800 V - Enables direct connection to rectified mains (up to 375 VDC peak) without external HV MOSFET. |
| RDS(on) | 6 Ω (typ.) at 25°C - Defines conduction loss and thermal dissipation in 15 W LED driver designs. |
| Power Factor | >0.9 - Achieved via analog line feedforward through CS pin, eliminating need for active PFC stages. |
| ILED Accuracy | ±3% - Tight constant-current regulation maintained across line/load/temperature without secondary sensing. |
| Switching Mode | Quasi-resonant (QR) with valley-skipping & burst mode - Reduces EMI and improves light-load efficiency down to ~100 Hz. |
| VCC Operating Range | 11.5–23 V - Supports self-supply from auxiliary winding while maintaining operation during low-output CV conditions. |
| OCP Threshold | 0.92–1.08 V on CS pin - Configurable overcurrent protection with hiccup-mode recovery for LED short-circuit safety. |
Pinout & Package
Package: SO-16N (16-pin small outline, exposed pad for thermal dissipation; RthJP = 10 °C/W, RthJA = 110 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (SOURCE) | MOSFET source node | Reference for current sense resistor (RSENSE) and PSR feedback network; tied to GND return path for signal integrity. |
| 2 (CS) | Current sense & feedforward input | Senses MOSFET current via RSENSE; also receives line voltage feedforward via ROS/RPF to shape input current waveform for PF >0.9. |
| 3 (VCC) | Supply voltage input | Powered by internal HV startup generator or auxiliary winding; regulated UVLO (12–14.8 V turn-on, 9–11 V turn-off) ensures safe start/stop. |
| 4 (GND) | Signal & power ground | Common return for gate drive, analog circuits, and RSENSE; must be isolated from noisy power loops per layout guidelines. |
| 5 (ILED) | CC reference capacitor node | Connects external CLED (10 µF min); internal circuit develops dynamic reference voltage for precise average LED current regulation. |
| 6 (DMG) | Demagnetization & output voltage monitor | Detects transformer reset for ZVS turn-on; sampled voltage feeds error amplifier for CV regulation; clamped (−60 mV / +3.3 V) for noise immunity. |
| 7 (COMP) | Error amplifier output | Drives external RC compensation network; controls switching frequency and mode transitions (QR → valley-skipping → burst). |
| 8, 9–11 (N.A.) | No-connect / ground tie | Pins 8, 9, 10, 11 must be connected to GND to ensure proper thermal and electrical performance. |
| 12 (N.C.) | Not internally connected | PCB clearance provision only; no electrical function; required for creepage/clearance compliance. |
| 13–16 (DRAIN) | MOSFET drain terminals | Four paralleled drain pins reduce conduction resistance and improve thermal spreading; also sink HV startup current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 800 V, 6 Ω MOSFET | Eliminates external HV switch and associated gate drive complexity; enables compact, cost-effective 15 W LED driver PCBs. |
| Primary Sensing Regulation (PSR) | Removes optocoupler, secondary shunt regulator, and current-sense resistor-reducing BOM count and improving long-term reliability. |
| Quasi-resonant + multimode control | Enables zero-voltage switching at heavy load, valley-skipping at medium load, and controlled burst mode at light load for <100 mW no-load consumption. |
| Open/short LED string protection | Automatically enters safe shutdown or hiccup mode upon LED string open (CV regulation failsafe) or short (OCP-triggered restart). |
| High-voltage self-supply | Internal HV startup generator charges VCC directly from DRAIN, sustaining operation even when auxiliary winding voltage collapses during CC regulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar primary-side regulated LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NCL30001DR2G | 700 V MOSFET, fixed-frequency CRM (not QR); requires external HV startup; no integrated DMG clamp. | Limited to PF >0.9 only with complex feedforward network; no built-in burst mode or open-string CV fallback. | Prefer HVLED815PFTR where QR efficiency, self-supply, and dual-mode protection are required. |
| Diodes Incorporated AL1676S16-13 | 650 V MOSFET, PSR-only (no CV regulation); no internal HV startup; lower RDS(on) (4.5 Ω) but no avalanche rating. | Not suitable for universal input >265 VAC; lacks short-LED protection and self-supply under low-VAUX. | Choose HVLED815PFTR for 800 V ruggedness, full fault coverage, and single-stage high-PF design. |
Compared with NCL30001DR2G and AL1676S16-13, the HVLED815PFTR uniquely integrates 800 V avalanche-rated switching, QR+valley+burst multimode control, and complete open/short LED protection - enabling simpler, more robust, and higher-PF 15 W LED drivers without secondary sensing.

FAQ
What is the maximum continuous output power supported by HVLED815PFTR?
The HVLED815PFTR is rated for up to 15 W continuous LED output power in properly heatsinked SO-16N layouts. This limit derives from its 0.9 W maximum power dissipation at TA = 50°C, 6 Ω RDS(on), and thermal resistance (RthJA = 110 °C/W). Derating is required above 50°C ambient or with insufficient copper area.
Does HVLED815PFTR require an external startup resistor?
No - the HVLED815PFTR integrates a high-voltage startup generator that draws current directly from the DRAIN pins. It begins charging VCC when DRAIN voltage exceeds 40–60 V, eliminating the need for external high-voltage resistors and associated power loss and board space.
How does HVLED815PFTR achieve high power factor without active PFC?
It uses analog line feedforward via the CS pin: external ROS and RPF resistors scale the rectified input voltage into the CS node, modulating peak MOSFET current proportionally to instantaneous line voltage. This shapes input current to closely follow input voltage, achieving PF >0.9 in single-range configurations.
Can HVLED815PFTR drive multiple parallel LED strings?
Yes - when configured for constant-voltage (CV) mode with appropriate output capacitance and current-limiting resistors, it can supply multiple parallel strings. However, for best current matching and thermal stability, ST recommends single-string constant-current (CC) operation per IC, or external current-sharing schemes for multi-string designs.
