Description
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.
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.
