HVLED815PFTR

Overview

The HVLED815PFTR is an off-line LED driver IC featuring a 16-SOIC package. It integrates an 800 V avalanche rugged Power MOSFET with a low voltage PWM controller. The device operates at a switching frequency of 166 kHz and supports PWM dimming. It utilizes primary sensing regulation (PSR) to eliminate the need for an optocoupler. The supply voltage range spans from 11.5 V to 23 V, with a junction temperature operating range of -40°C to 150°C.

Feature Summary

• Integrates an 800 V avalanche-rated Power MOSFET with a PWM controller in a single package
• Employs patented primary sensing regulation (PSR) technique to achieve accurate current control without an optocoupler
• Features internal high-voltage startup circuitry to reduce external component count
• Provides protection against LED string faults including open or short conditions

Applications

• High power factor isolated LED drivers using flyback topology
• Triac-dimmable lighting solutions for AC line inputs
• Compact LED replacement lamps for incandescent or CFL equivalents
• General-purpose off-line power conversion for LED strings

Procurement Notes

Verify the specific suffix 'P' indicates the tube packaging variant when cross-referencing with distributors, as 'HVLED815PFTR' typically denotes tape and reel. Confirm RoHS compliance status and MSL rating via the official datasheet before integration. Ensure the design accounts for the 16-SOIC thermal characteristics and verify that the 800 V MOSFET rating aligns with the target mains voltage stress requirements.

Selection Notes

Select this component for designs requiring high power factor correction and isolation without optocouplers. It is suitable for applications needing wide input voltage ranges and efficient primary-side regulation. Consider the integrated 800 V switch for cost-effective bill-of-materials reduction. Evaluate the 166 kHz frequency for magnetics sizing and ensure compatibility with required dimming protocols such as PWM or Triac.
