Zero-ripple LED driver for 18 W lamp replacement using HVLED001A quasi-resonant flyback controller and STF10LN80K5

The form factor and specific component selection render this board suitable for rounded enclosures, as replacements for fluorescent lamp tubes (T8 size).
As typical applications are totally sealed, non isolated, high power factor SEPIC topology is used to achieve a high power factor, low THD (< 20%) and very high efficiency, as well as allowing input current ripple steering, which dramatically reduces EMI, even with small input filters.
The HVLED001A controller protections manage input voltage variations, excessive input voltage (overvoltage like surge or bursts) and very low input voltages.
The efficiency of the application is very high, compared with similar wattage applications.
