The STEVAL-ILL080V1 provides a 200 mA, ripple-free output current to supply a single LED string between 75 and 93 V. 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.
LED string voltage: 83 V ±10% No load output voltage: 110 V High power factor, low THD No-load: better than 300 mW at 230 Vin Full load efficiency: > 85 % Short circuit protection with auto restart
