STEVAL-ILB010V1
2 x 58 W high frequency ballast for T8 fluorescent tubes based on
L6562A, L6569, and STL11NM60N in PowerFlat™ HV package
Data brief
light for the same input power when driven above
20 kHz, instead of 50/60 Hz. Operation at high
frequency also eliminates light flickering and
audible noise.
Features
• Mains voltage range: 185 to 265 Vac
• Minimum mains frequency: 47 Hz
• Rated output power: 116 W
• Regulated DC output voltage: 400 V
• Efficiency: 90%
• Power factor: 0.99
• RoHS compliant
Description
The STEVAL-ILB010V1 demonstration board is
an electronic ballast capable of driving two 58 W
linear T8 fluorescent tubes. It consists of two
sections: a power factor correction (PFC) pre-
regulator employing the L6562A, and a lamp
ballast stage based on the L6569. The purpose of
the demonstration is to provide a platform for
testing the electrical features of the new
PowerFlat™ package, and to allow comparison of
its thermal behavior versus the “DPAK” package.
Fluorescent lamps are more and more frequently
driven by electronic ballasts rather than
electromagnetic ballasts, mainly because
fluorescent lamps can produce around 20% more
