STMicroelectronics HVLED815PF | Demoboard EVLHVLED815W10A
Offline LED driver with primary-sensing and high power factor up to 15 W
Overview
| Topology | Other Topology |
| IC revision | 5 |
Description
The HVLED815PF device is a high voltageprimary switcher intended for operating directlyfrom the rectified mains with minimum externalparts and enabling high power factor (> 0.90) toprovide an efficient, compact and cost effectivesolution for LED driving. It combines a high performancelow voltage PWM controller chip andan 800 V, avalanche rugged Power MOSFET, inthe same package. There is no need for theopto coupler thanks to the patented primarysensing regulation (PSR) technique. The deviceassures protection against LED string fault (openor short).
Features
High power factor capability (> 0.9)
- 800 V, avalanche rugged internal 6 PowerMOSFET
- Internal high voltage startup
- Primary sensing regulation (PSR)
- ± 3% accuracy on constant LED output current
- Quasi-resonant (QR) operation
- Optoc oupler not needed
- Open or short LED string management
- Automatic self supply
Typical applications
- AC-DC LED drivers up to 15 W
- AC-DC LED driver bulb replacement lamps up to 15 W, with high power factor
