HVLED815PF

Overview

The HVLED815PF is an off-line LED driver IC featuring a 16-SOIC package. It integrates a high-voltage primary switcher with an 800 V avalanche rugged Power MOSFET and a low voltage PWM controller. The device operates directly from rectified mains, utilizing primary sensing regulation (PSR) to eliminate the need for an optocoupler. Key electrical parameters include a supply voltage range of 11.5V to 23V, a switching frequency of 166kHz, and ±3% accuracy on constant LED output current. It supports quasi-resonant operation and internal high-voltage startup.

Feature Summary

• Integrates an 800 V avalanche rugged Power MOSFET with a PWM controller in a single package
• Utilizes patented primary sensing regulation (PSR) technique to achieve accurate LED current control without an optocoupler
• Provides protection against LED string faults, including open or short circuit conditions
• Features automatic self-supply and internal high-voltage startup capabilities

Applications

• High power factor isolated LED drivers using flyback topology
• Non-isolated LED drivers compatible with Triac-based dimmers
• Compact LED replacement solutions for incandescent or compact-fluorescent lamps

Procurement Notes

Verify the specific suffix 'PFTR' indicates tape and reel packaging when ordering. Confirm the component status as active with STMicroelectronics.
